It marks a dramatic turnaround since the 2019 general election, when Boris Johnson won the Tories a healthy 80-seat majority and Jeremy Corbyn led Labour to its worst result since 1935.
The exit poll suggests Labour is on course for 410 seats, with the Tories reduced to 131.
It will mean a Labour prime minister in No 10 for the first time in 2010 and the Conservatives facing a possible civil war as the fight for the future direction of the party and the battle to potentially replace Mr Sunak gets under way.
After 14 years in power it was always going to be a difficult election for the Conservatives, but the sometimes shambolic campaign – triggered at a time of Mr Sunak’s choosing – has contributed to their party’s likely defeat.
From the rain-drenched speech announcing the surprise July 4 poll, through the D-Day debacle as he left Normandy early to record a TV interview to confused campaign messaging about a Labour “supermajority”, Mr Sunak struggled to convince the electorate he was the right man to lead the country.
Going for a summer election rather than waiting until the autumn was always a gamble, and the Prime Minister was not helped by the scandal of Tory candidates and officials allegedly heading to the bookies armed with inside knowledge of the date.
Mr Sunak is expected to resign after leading his party to defeat, but many of the contenders jostling to replace him are nervously awaiting their own constituency results to see if their leadership dreams survive the night.
The likes of Penny Mordaunt, Grant Shapps, Suella Braverman, Steve Baker and Robert Jenrick all face battles to return to Parliament.
Former home secretaries Suella Braverman and Dame Priti Patel, security minister Tom Tugendhat and Health Secretary Victoria Atkins could survive to fight for the leadership.
