Here's a look at who lost their seats.
Liz Truss
Former prime minister Liz Truss has lost her seat, with people slow-clapping as they waited to hear results.
Once leader of the Tory party, Ms Truss narrowly lost to Labour's Terry Jermy by just 630 votes.
Jacob Rees Mogg
Rees Mogg is perhaps the most high-profile Tory backbencher to have lost his seat.

Labour unseated him in North East Somerset and Hanham, which he has represented since 2010.
The Eton-educated arch Brexiteer resigned from government when Mr Sunak took office, having served as business secretary under Liz Truss and as Brexit minister and leader of the House of Commons under Mr Johnson - who knighted him in his resignation honours list.
Grant Shapps
Defence Secretary Grant Shapps has been voted out of parliament after 19 years as the MP for Welwyn Hatfield in Hertfordshire.
He lost by a margin of 3,799 votes to Labour, meaning the Tories must say goodbye not only a veteran cabinet minister, but also someone considered to be one of the party's strongest communicators.
This strength saw him put in charge of various government departments over the years, including transport, energy, business and the Home Office (albeit briefly).
Alex Chalk
As predicted by the exit poll, Justice Secretary Alex Chalk has lost his seat in Cheltenham to the Lib Dems.
He was the 11th person to take up that brief in 13 years after Dominic Raab resigned over bullying allegations - and the job did not come without its challenges amid overcrowding in prisons and a record crown court backlog.
First elected in 2015, Mr Chalk was also the solicitor general under Boris Johnson, but joined the mass exodus of ministers that led to his resignation.
Gillian Keegan

Education Secretary Gillian Keegan has also fallen victim to the Lib Dem's plan to smash the Tory "blue wall" in southern England.
The Lancashire-born cabinet minister has been unseated in Chichester in South West Sussex, which she has represented since 2017.
Ms Keegan was relatively unknown until she was put in charge of the education brief by Rishi Sunak. In that role, she has had to deal with teachers striking and the RAAC crisis in schools - though others may remember her for a rather sweary outburst.
Simon Hart
Simon Hart has been the MP for Carmarthen West and South Pembrokeshire in Wales since 2010. Boundary changes meant the make up of his new seat Caerfyrddin took in a larger proportion of Plaid Cymru supporters, helping the Welsh nationalist party come out on top here.
As the chief whip, Mr Hart has been in charge of party discipline over the last few years and before that served as Welsh Secretary
Johnny Mercer
Johnny Mercer unexpectedly won Plymouth Moor View from Labour in 2015 and has increased his majority at each election since, but the Devon constituency has turned back red.
The veterans minister has been a champion of the British military community and has served in his post since July 2022 (bar the two months he was controversially sacked by Liz Truss).
Since then, the combative ex-soldier has continued to hit the headlines a lot, notably because he is potentially facing time in prison over his decision not to hand over certain information to the independent inquiry relating to Afghanistan.
Penny Mordaunt

Commons leader Penny Mordaunt has been unseated by Labour in Portsmouth North - a fate that will upset Tory moderates who saw her as a potential successor to Rishi Sunak.
An MP since 2010, the Royal Navy reservist became the first ever female defence secretary in the dying days of Theresa May's government.
Although she was demoted by Boris Johnson a few months later, the two-time leadership contender maintained a high media profile as Leader of the House of Commons under two subsequent prime ministers (notably for her sword-carrying skills at the King's coronation).
Lucy Frazer
Culture Secretary Lucy Frazer is another heavyweight who's been unseated by the Lib Dems.
Sir Ed Davey's party have gained her Ely and East Cambridgeshire constituency, which she has represented since 2015.
Ms Frazer held multiple ministerial jobs before she was elevated to cabinet status in Mr Sunak's reshuffle last year - a role in which she has faced criticism after accusing the BBC of bias.
Mark Harper
Transport secretary Mark Harper lost his seat in the Forest of Dean to Labour - by a very small margin.
Matt Bishop, the Labour candidate, holds a majority of just 278 in the constituency now.
Mr Harper, a close Sunak ally, is known for leading the COVID Recovery Group of backbench MPs who challenged lockdown restrictions during the pandemic.
