28 March 1979 was one of the most dramatic nights in Westminster history.
James Callaghan's Labour government lost a confidence motion by one vote and was forced to call an early General Election that would sweep Margaret Thatcher to power.
BBC Parliament is marking the 30th anniversary of that night with a special evening of programmes, The Night the Government Fell.
1800 GMT A Parliamentary Coup
tells the story of what happened that night, with testimony from former Downing Street insiders, ministers and party managers about the increasingly frantic attempts to secure the vote for Labour.
In five years as a minority Government, Labour had struck deals with various smaller parties in order to survive but, by March 1979, after a winter of industrial strife, their luck was running out.
Even on the day of the vote, it looked too close to call.
It was only as the night wore on that it became clear that two key abstentions - and the absence of a gravely ill MP - would cost them the vote.
Immediately following the Commons debate,
(the predecessor of Newsnight) was broadcast live from Westminster on BBC One.
It featured interviews with Michael Foot, Lord Carrington, John Pardoe, Francis Pym and Lord Diamond on the dramatic events in the Commons and the fall of the Government.
Newspaper journalists Peregrine Worsthorne and John Cole were also interviewed.
This is another chance to see this programme, presented by Robin Day and Donald MacCormick, in full.
1930 GMT Turning Points: The 1979 General Election
explains how failure to secure devolution for Scotland lost Labour the support of the Scottish National Party in the run-up to the vote of no confidence.
George Cunningham, a Labour MP at the time, discusses the context of the historic vote in this History of Parliament Trust lecture.
BBC Parliament presents highlights of the
1979 No Confidence Debate
in the House of Commons.
Among the notable speakers featured were Prime Minister James Callaghan, leader of the opposition Margaret Thatcher, Liberal leader David Steel and Labour's Michael Foot.
