Irish Foreign Minister Dermot Ahern and Northern Ireland Secretary Peter Hain have held further talks on the political process.
Peter Hain and Dermot Ahern held talks in London
At the meeting in London on Thursday, the men discussed recent efforts to restore power-sharing to NI.
Talks hosted by the governments at Stormont on Monday broke down.
A spokesman for Mr Ahern said the meeting was "part of intensified efforts to restore the executive and assembly as soon as possible".
The politicians held their breakfast meeting at the Northern Ireland Office at Millbank.
Mr Ahern met Parades Commission chairman Roger Poole in Dublin on Tuesday.
The Northern Ireland secretary has said the government may be prepared to form a shadow assembly before power-sharing is fully restored.
Plans for round-table talks by Northern Ireland political parties at Stormont earlier this week collapsed amid acrimony.
The plan was to have the DUP, SDLP, UUP and Alliance at one session of talks on Monday, without Sinn Fein.
This would have been followed by a second round in which Sinn Fein replaced the DUP - which refused to sit down with the republican party.
However, Sinn Fein angrily rejected the plan. Party leader Gerry Adams accused the government of "pandering to the DUP".
