Keir Starmer is on course for a landslide election victory as voters finally boot out the Tories.
The exit poll has predicted Labour will secure a huge majority of around 170.
If confirmed, the result would mark the most extraordinary comeback for Labour just five years after it suffered its worst result in living memory.
When the polls closed at 10pm, it became clear that Rishi Sunak was heading for crushing defeat as voters delivered their damning verdict on 14 years of Tory rule. He will be kicked out of Downing Street tomorrow. Mr Starmer, 61, is expected to go to Buckingham Palace at lunchtime to be formally appointed Prime Minister by the King.
Later, he will appoint key ministers including Rachel Reeves, who will become the first female Chancellor of the Exchequer in history, and Angela Rayner, who will be Deputy Prime Minister. Mr Sunak will announce he is quitting as Tory leader, triggering weeks of bitter infighting as the party tears itself apart over who should replace him.

MPs will return to Westminster on Tuesday and begin the process of swearing in, before the King formally opens Parliament on July 17.
The government is expected to make early announcements on housebuilding, as well as how it intends to tackle the crisis in prisons before the Commons rises for a shortened summer break at the end of the month.
The new Prime Minister will fly to Washington DC on Tuesday where he will meet fellow world leaders including US President Joe Biden at a summit marking the 75th anniversary of Nato. Mr Starmer is also expected to make one of his first foreign trips to Kyiv to demonstrate Britain’s continued commitment to Ukraine.
When he walked out of Downing Street in the pouring rain to call the election six weeks ago, Mr Sunak took a huge gamble that he could take chunks out of Mr Starmer’s commanding poll lead. But Labour remained well ahead throughout the entire campaign as the Tory PM made a series of major errors, including leaving D-Day 80th anniversary commemorations early and his botched handling of the election betting scandal.
Mr Starmer looked happy and relaxed as he cast his vote in his constituency of Holborn and St Pancras in north London, strolling to the polling station with his wife Vic. Mr Sunak began his last full day as Prime Minister by voting early with his wife Akshata at Kirby Sigston Village Hall in his Richmond and Northallerton constituency in North Yorkshire, before returning to their Grade-II listed manor house nearby.
Liberal Democrat leader Ed Davey and his wife went to a polling station in Surbiton.
At the last election, Boris Johnson won 43.6% of the vote and 365 seats, a majority of 80. Labour under Jeremy Corbyn picked up 32.1% and 202 seats.
Since taking over as party leader in April 2020, Mr Starmer has transformed Labour.
The former Director of Public Prosecutions has pledged to get on with the job of fixing Britain as soon as he enters Downing Street. He is promising to revive the economy, put 6,500 more teachers in schools and bring down NHS waiting lists by putting on millions of extra hospital appointments. Labour has also vowed to put more police on the streets, bring down household bills with GB Energy and restore control of the country’s borders.
Labour last swept to power in 1997 when Mr Blair got 418 seats in his historic landslide victory, which gave him a majority of 212.
Prime Ministers need 326 MPs to be sure of a majority.
