Professor Richard Toye, head of history at the University of Exeter, explains how a vote of no confidence works and which prime ministers in history have fallen victim...


What is a vote of no confidence?

There are two types of votes of no confidence: one, in the party leader the other is a parliamentary no-confidence vote, which signifies that the government itself has lost the support of the Commons.

Under the internal rules of the Conservative Party, a vote of no confidence in the party leader is triggered in the event that at least 15 per cent of Conservative MPs write to Graham Brady, chairman of the 1922 Committee, formally calling on the party leader to stand down. The 1922 committee is a committee of all backbench Conservative MPs that meets weekly when the Commons is sitting.

What is a parliamentary no confidence vote?

A motion of no confidence, or censure motion, is a motion moved in the House of Commons with the wording: “That this House has no confidence in HM Government”. It signifies that the government has lost the support of the Commons (the legislature), without which it is impossible to operate effectively. Retaining the confidence of the Commons is a core principle of the UK constitution.

If a motion stating “That this House has no confidence in HM Government” is lost by the government, or if a major legislative proposal is defeated, the government must either resign or ask the Queen to dissolve Parliament, thus triggering a general election. She would almost certainly grant such a request.

Prof Richard Toye explains: “The basic principle is this: the government of a country has to have the confidence of the House of Commons. If the government has lost its majority or does not have a reliable majority, that is the cue for either the government to fall and be replaced, or for a general election to be called.

When was the first vote of no confidence in Britain?

Votes of no confidence – or their historical equivalent – were a fairly regular occurrence in the 19th century, but from 1900 to the present day they have not come about very often, says Toye.

Sir Robert Walpole agreed to resign in 1742 after losing a vote in the Commons that was effectively considered a motion of no confidence. Toye explains: “There is a distinction to be made between a formal vote of no confidence, and a situation in which the government is looking to pass a key proposal or piece of legislation, or faces censure from the Opposition, and to lose would suggest they have lost the confidence of the House of Commons.”

In 1782, a motion censuring the government of Lord North for its conduct during the war with America was the first time a government was brought down by a vote of no confidence, says the Institute for Government. “Since then, there have been 20 government defeats on a vote of confidence all leading to either dissolution or resignation (and if the latter, a second government being formed in their stead).”

Other notable incidents in modern history include the (effective) vote of no confidence in the Conservative government of Stanley Baldwin in 1924 following the loss of his majority in the general election of December 1923. The election left the Conservative government outnumbered in the Commons by Labour and the Liberals, and when parliament met it was defeated on the King’s Speech (that is, the government’s programme of policies). Baldwin resigned and Ramsay MacDonald formed a minority government, becoming the first Labour prime minister. He in turn lost a confidence vote that autumn and a further election followed.

Similarly, the Norway Debate of 1940 – a debate held on 7 and 8 May between MPs on Britain's failed campaign against German invasion forces in Norway – turned into a vote of confidence on prime minister Neville Chamberlain. On that occasion the motion on the Order Paper was simply the proposal ‘that this House do now adjourn’, on which Labour called a division (or vote).”

Chamberlain won, but with a substantially reduced majority and, with his credibility badly damaged, resigned two days later. He was replaced as prime minister by Winston Churchill. Churchill promptly invited the leaders of the Labour and Liberal parties – Clement Attlee and Archie Sinclair – to form a coalition government, with Chamberlain serving in Churchill's cabinet as lord president of the council.

When did a vote of no confidence last lead to a general election?

The last time a vote of no confidence led to a general election was in 1979. The Labour government led by James Callaghan faced a vote of no confidence on 28 March 1979 following a defeat over a referendum for devolution to Scotland and lost by just one vote. Following the vote, which was brought by opposition leader Margaret Thatcher, Callaghan was forced to call a general election which was won by Thatcher’s party.

“Opposition parties have, through history, often put down votes of no confidence, but generally they tend not to succeed because members of the governing party see that the government’s life is in danger, as it were, and so they ‘rally round’,” Toye explains.

Votes of no confidence were put down on two occasions in 1942 (“when the war was going badly for Britain”, says Toye). “These were dangerous moments for Churchill, but he consistently managed to survive the votes. There was also a case that was unrelated to the conduct of the war. In 1944 the government opposed an amendment to its Education Bill, an alteration which would have introduced equal pay for female teachers. The government lost narrowly; Churchill was furious. He went back to the House of Commons and basically said he wanted the matter to be treated as a vote of confidence, and succeeded in getting the amendment reversed. He effectively 'brow-beat' the House of Commons into giving him his way.”

Another curious incident in history involves Margaret Thatcher, who notably faced down Labour’s vote of no confidence in her government in 1990 – even though she had resigned as prime minister earlier that day. On 22 November, Thatcher announced her decision to stand down as prime minister after her cabinet refused to back her in a second round of leadership elections. But later that day Labour’s motion of no confidence was defeated. Nevertheless, John Major succeeded as Tory leader five days after Thatcher's resignation.

Were votes of no confidence used before the 19th century?

Yes, a number of politicians were subject to votes of no confidence prior to the 19th century – these include the aforementioned Robert Walpole in 1742 (he resigned afterwards); William Pitt the Younger in 1784 (he avoided resignation by asking for a dissolution of parliament and the ensuing election bolstered his government with a safe majority in the Commons); and the Duke of Wellington in 1830 (he resigned the day after the vote).

Toye says: “It’s important to remember that in previous centuries MPs were less blindly loyal to their party – in the 19th century, for example, there weren’t really ‘career politicians’ in the sense that we have them today. MPs, who weren’t paid, weren’t under the same pressure to remain loyal in order to keep their jobs, and party discipline was therefore less rigid. In this sense, 19th-century governments were less stable than modern governments.”

How do votes of no confidence work today?

“Post-1900, governments have generally been unlikely to lose a vote of no confidence unless they are in a minority government,” says Toye. “The three successful votes of no confidence in recent history – two in 1924, and 1979 – were against minority governments. Similarly, the reason Theresa May was in danger in December 2018 is because of her reliance on Northern Ireland’s DUP (Democratic Unionist Party). Had May not called a general election in 2017, from which she emerged with a minority government, she would not have been so vulnerable.”
