Bertie Ahern and Tony Blair chaired the Leeds Castle talks
27 July 2004: The Northern Ireland Office confirms that the British and Irish prime ministers will host a new round of political talks aimed at restoring the assembly in late September. The venue is later revealed as Leeds Castle, Kent. Preliminary talks in Belfast start at the beginning of September.
10 September 2004: Prime Minister Tony Blair says the Leeds Castle talks will show if there is the will among the political parties to end violence and share power. Paul Murphy says the negotiations will be the most critical in the peace process.
18 September 2004: Three days of intensive negotiations at Leeds Castle end with the parties failing to reach agreement. Despite this, there is a mood of cautious optimism among party leaders and the prime ministers, and further talks aimed at resolving various sticking points are to continue at Stormont.
4 October 2004: DUP leader Ian Paisley has a landmark meeting in Dublin with Taoiseach Bertie Ahern. It was the first time Mr Paisley had led a political delegation to meet an Irish prime minister in Dublin. It came amid continuing efforts to iron out the sticking points encountered at Leeds Castle.
18 October 2004: Northern Ireland Secretary Paul Murphy says he hopes a breakthrough in the political process is just weeks away, although he concedes two days later that the governments still face some "very difficult" issues in bridging the gap between the DUP and Sinn Fein.
23 October 2004: Sinn Fein chairman Mitchel McLaughlin says the DUP is seeking to humiliate the IRA over its demand for visible decommissioning. DUP deputy leader Peter Robinson says his party's position on IRA disarmament and activity had been "clear and consistent throughout the negotiating process".
28 October 2004: The Independent Monitoring Commission says the IRA shows no signs of winding down its capability. The ceasefire watchdog's third report said the UDA remained heavily involved in organised crime and the UVF remained a "ruthless organisation retaining a capacity for more widespread violence". Paramilitary violence had "considerably reduced" in the last six months but remained "at a disturbingly high level", the commission found.
8 November 2004: Bertie Ahern says it would be an "enormous tragedy" if a breakthrough was not made in the Northern Ireland political process in the next two weeks.
12 November 2004: The British Government officially recognises the UDA's ceasefire in a bid to bring loyalists more fully into the political process. Paul Murphy says he believes that Northern Ireland's biggest loyalist paramilitary group is ready to move away from violence. Government recognition for the UDA ceasefire was removed in October 2001 because of its involvement in violence. The group declared a new ceasefire in February 2004.
17 November 2004: The two governments put their proposals aimed at breaking the political stalemate to the DUP and Sinn Fein. The plans followed two months of continuing negotiations aimed at exploring a way around the stumbling blocks faced at Leeds Castle. The two parties begin consulting with their members about the blueprint, which is not made public.
24 November 2004: Ian Paisley hands Tony Blair his party's response to the proposals. Both parties continue high-level negotiations with the governments, although no direct negotiations take place because the DUP refuses to talk directly with Sinn Fein. Both parties are backing the creation of a £1bn peace fund as part of the price tag for any deal.
26/28 November 2004: US president George W Bush telephones Ian Paisley and Gerry Adams to offer his support to efforts to achieve a breakthrough in the process. Both parties have concerns about the British-Irish proposals which they want resolved.
29 November 2004: Gerry Adams holds a groundbreaking first meeting with the head of Northern Ireland's police force. Top of the agenda is demilitarisation - the scaling down of the military presence in Northern Ireland. He describes his meeting with PSNI Chief Constable Hugh Orde at Downing Street as "useful". The meeting came as Ian Paisley met the head of the decommissioning body to discuss any possible IRA disarmament.
30 November 2004: Ian Paisley gives the message to the IRA that a deal to restore devolution is "now or never". But he also repeats his call for the IRA to "wear sackcloth and ashes" and repent for its actions. Gerry Adams says Mr Paisley's comments are "offensive".
Ian Paisley insisted on photographic proof of IRA decommissioning
1 December 2004: Gerry Adams says the political process has reached a "defining point" but the current talks could go no further. "As far as we are concerned we have made our final representations on the governments' text," he said.
4 December 2004: Ian Paisley meets decommissioning body chief General John de Chastelain for the second time in less than a week. He said it was unrealistic to set deadlines for a political deal when the IRA has still not discussed decommissioning with General de Chastelain. Meanwhile, Gerry Adams appealed to republicans not to be provoked by the "unacceptable language" used by Mr Paisley. He said comments made by Mr Paisley that he would have to "swallow hard" to do business with republicans, were an acknowledgement of the prospect of Sinn Fein in government.
7 December 2004: Gerry Adams recommends that his party should accept the British-Irish proposals, saying that its negotiations had resolved issues of concern and succeeded in strengthening key provisions of the Agreement. It came hours after Ian Paisley said the main stumbling block to any deal remained decommissioning.
8 December 2004: Tony Blair and Bertie Ahern travel to Belfast to make their proposals public. These include a plan for the IRA to allow photographs to be taken of its weapons being put beyond use in the presence of independent witnesses. However, Ian Paisley's DUP say they are not signing up, because the IRA is refusing photographs of decommissioning. Mr Paisley says "significant progress" has been made on all aspects of the comprehensive agreement with the exception of how decommissioning would be handled. Gerry Adams says that progress is being held up by "the demand for a process of humiliation".
9 December 2004: The IRA says it is committed to the peace process but would "not submit to a process of humiliation". In a statement in republican newspaper An Phoblacht, the organisation says in the event of a deal, it would end its activities, complete decommissioning by December "if possible" with two clergymen overseeing the process. It says DUP demands for photographic proof of decommissioning were "never possible" and an excuse for rejecting a power-sharing deal which could "remove the causes of conflict".
13 December 2004: The British and Irish prime ministers hold separate meetings with Sinn Fein leaders Gerry Adams and Martin McGuinness in London and Dublin. After his meeting, Bertie Ahern says he accepts that the issue of photographs for verifying decommissioning is not workable. Both he and Mr Adams said they would continue to close the gap on the remaining issues before Christmas.
The Northern Bank robbery
21 December 2004: An armed gang steals £26.5m from the Northern Bank in Belfast city centre, casting a long shadow over the political negotiations amid speculation the IRA was responsible. The IRA later says it was not involved in the bank robbery and Sinn Fein leaders say they believe this denial.
7 January 2005: Chief Constable Hugh Orde says the IRA carried out the Northern Bank robbery. A Downing Street statement says Tony Blair had made it clear the political institutions could only be restored if there was a "complete end" to all paramilitary and criminal activity. Bertie Ahern says trust and confidence in the peace process has been damaged.
The IRA was widely blamed for the £26.5m Northern Bank robbery
30 January 2005: Difficulties in the process are compounded when IRA members are implicated in the killing of Robert McCartney, who was stabbed to death near a Belfast bar.

17 March 2005: US President George W Bush meets Robert McCartney's sisters and partner at the White House on St Patrick's Day, attracting global media interest. Unlike previous years, Northern Ireland's politicians were not invited to the celebrations.
6 April 2005: Gerry Adams appeals to the IRA to help rebuild the political process, asking it to "fully embrace and accept" democratic means. He made the call at the outset of campaigning for the Westminster election. The call followed a difficult few months for the party, which had come under increasing pressure over claims of continued IRA criminality.
6 May 2005: The DUP emerges as the big winner in the general election, winning nine constituencies. Its biggest scalp is Ulster Unionist leader David Trimble, who later steps down after defeat in the Upper Bann constituency. He is later replaced as leader by Sir Reg Empey, who is left to oversee a party which has just one remaining MP. Meanwhile, Sinn Fein becomes the biggest nationalist party in Westminster, winning five seats, although the SDLP avoid the electoral disaster predicted by some commentators, securing three seats. Paul Murphy is replaced as Northern Ireland Secretary by Peter Hain, who will combine the job with his other duties as Welsh secretary.
IRA announces end to armed campaign
28 July 2005: The IRA formally orders an end to its armed campaign and says it will pursue exclusively peaceful means. It says it will follow a democratic path, ending more than 30 years of violence. Gerry Adams hails the move as a "courageous and confident initiative". Tony Blair says it is a "step of unparalleled magnitude". A sceptical Ian Paisley says the IRA had "reverted to type" after previous "historic" statements. The IRA made its decision after an internal debate prompted by Mr Adams's call in April to pursue its goals exclusively through politics.
The IRA statement was delivered by former hunger striker Seanna Walsh
1 August 2005: The government sets out a two-year plan to scale down the Army's presence in Northern Ireland and change the way the province is policed. The number of troops will be reduced from 10,500 to about 5,000 if the security climate is right. The government says it is also aiming to repeal within two years counter terrorist legislation particular to Northern Ireland. Army posts will also be closed and police stations defortified. A day later, it is announced that the Northern Ireland-based battalions of the Royal Irish Regiment are to be disbanded as part of the Army response to the IRA ending its armed campaign. The Army will end its support role to the police on 1 August 2007, the same day that the battalions will disband. Unionists react angrily to the move, which nationalists welcomed.

The two churchmen who witnessed the process, Catholic priest Father Alec Reid and ex-Methodist president Rev Harold Good, say they are "satisfied that the arms decommissioned represent the totality of the IRA's arsenal". Ian Paisley says questions remain without photographic proof, an inventory and details on how the weapons were destroyed.

8 December 2005: Three Belfast men at the centre of an alleged IRA spying incident at Stormont are acquitted of all charges. The men, whose arrests led to the collapse of the power-sharing executive in 2002, claimed the case against them had been politically motivated. At an unlisted hearing at Belfast Crown Court, Ciaran Kearney, William Mackessy and Sinn Fein's Denis Donaldson are told all charges are being dropped. The prosecution offered no evidence "in the public interest".
Denis Donaldson publicly admitted being a spy
16 December 2005: Veteran Sinn Fein figure Denis Donaldson admits he was a paid British agent for two decades. He is expelled from the party.

Mr Donaldson said there had not been any republican spy ring at Stormont.
11 January 2006: The government drops its controversial proposals on paramilitary fugitives, which would have seen those accused of paramilitary crimes before 1998 appear in front of a special tribunal, then be freed on licence. Mr Hain told Parliament the legislation dealing with so-called "on-the-runs" was necessary but Sinn Fein's rejection of it made it unworkable. The legislation had been widely opposed.
4 April 2006: Former senior Sinn Fein figure Denis Donaldson is found shot dead in a remote cottage in County Donegal. The IRA issued a statement saying it had "no involvement whatsoever" in Mr Donaldson's death, which came less than 48 hours before a planned visit to Northern Ireland by Tony Blair and Bertie Ahern to unveil their plans for reviving the assembly at Stormont.
6 April 2006: Tony Blair and Bertie Ahern arrive in Northern Ireland to unveil their blueprint for restoring devolution. In it, assembly members are given until 24 November to set up a power-sharing executive. They confirm the assembly is to be recalled on 15 May with parties being given six weeks to elect an executive. If that fails, the 108 members get a further 12 weeks to try to form a multi-party devolved government. If that attempt fails, salaries will stop. They say the British and Irish governments would then work on partnership arrangements to implement the Good Friday Agreement.
10 May 2006: Gerry Adams says his party would not be participating in the discussion of issues such as education reform water charges, health and rates increases because "that would be pointless". He says he will nominate Ian Paisley for the position of first minister when the assembly returns, but Mr Paisley insists there will be no first or deputy first minister until Sinn Fein "met its obligations".

Party leader Gerry Adams says he will put forward a motion asking for a special party-wide conference "on the policing issue". Sinn Fein support for policing is viewed as removing one of the main obstacles to restoring devolution.
4 January 2007: Tony Blair flies home a day early from holiday in Florida to try to rescue hopes of devolution returning by the end of March. The move comes after doubt is thrown on the Sinn Fein policing conference in the wake of what the party says is lack of a "positive enough" response from DUP leader Ian Paisley. If the conference does not go ahead, the March election may be in doubt.
8 January 2007: DUP leader Ian Paisley denies he ever agreed that policing and justice powers would be transferred to the Northern Ireland Assembly by 2008.
