Since World War Two, just three Labour leaders have won majorities in the House of Commons.
Here are Labour's top three most electorally successful party leaders since the Second World War.
1. Clement Attlee
At the end of World War Two – after ten years without an election – Clement Attlee won a stunning victory, replacing Winston Churchill as prime minister. Atltee is remembered for starting the NHS and rebuilding Britain after the war, but he is also known for being the first Labour leader to win a majority. He did this once in 1945 (winning 393 seats) and again in 1950, but lost in 1951 after attempting to boost his slim majority.
2. Harold Wilson
The next Labour leader to win an election was Harold Wilson who dominated Labour party politics for the best part of two decades. Out of the five elections he fought as leader, Wilson won four, securing a majority in three of them.
Shocking the nation, Wilson stepped down in 1976, and was replaced by James Callaghan, who went on to lose the election in 1979 to Margaret Thatcher.
3. Tony Blair
Callaghan’s leadership was followed by Michael Foot’s, who led the party to a disastrous defeat in 1983. He was replaced by Neil Kinnock, who went on to lose two elections, taking the party slightly closer to power each time. He was then replaced by John Smith, who tragically died before fighting the next election, and was subsequently replaced by Tony Blair.
Blair won three elections, all with large majorities, the likes of which have not been seen since. In 2015, Ed Miliband led Labour to defeat, but two year’s later, Jeremy Corbyn won Labour its highest vote share since 2001.
Could Corbyn be the fourth post-war Labour leader to win an election?
The next election is not due until 2022, but Theresa May's slim majority with the DUP makes the option of an early election more likely.
