After 18 years of rule by this party, Brits went to the polls in a general election.
This Prime Minister called the election in March 1997, reaching the end of Parliament's five-year term.
However, Major's Conservative Party was trailing significantly behind in the polls to this party.
After this Labour leader had passed away, the Labour Party elected Tony Blair as leader.
Blair moved the party closer to the political centre and rebranded the party as this.
The Conservatives responded with a poster campaign with the slogan 'New Labour, New Danger', depicting Blair with these features.
Meanwhile, a slick Labour campaign featured a broadcast with this memorable song by D:Ream.
The Tories had further problems with divisions in the party over whether Britain should join this monetary union.
The election was held on this day.
On the morning of the May 2nd, Brits woke up to a Labour landslide, with Blair's party winning this many seats.
The Tories were decimated, with their number of seats being halved to this number.
Memorably, this Conservative Defence Secretary lost his seat with a 17.4% swing. In 1999, it was voted by Channel 4 viewers to be the third-greatest television moment of all time.
The Tories were also slightly hindered this party, led by James Goldsmith, who took 2% of voters, who were almost all Conservative.
Although they had a smaller vote share, tactical voting helped this party, led by Paddy Ashdown, to a record 46 seats.
After a humiliating defeat, John Major resigned as leader of the Conservatives, and was replaced by this man.
Labour went on to win two more elections under Blair's leadership. In 2007, he stepped down and was replaced by this man, who became Chancellor of the Exchequer after the 1997 election.
The election marked the start of 13 years of Opposition for the Tories, who were not able to form a government until this man led them into coalition in 2010.
