Several prominent MPs are facing reselection battles ahead of the next general election under new constituency boundary proposals in England and Wales.
Labour leader Jeremy Corbyn and ex-chancellor George Osborne are among those whose seats would be abolished.
Most constituencies are affected by the bid to cut the number of MPs in the Commons and create equal-sized seats.
Labour - expected to be hit hardest - said the proposals were "undemocratic".
But the government said they would "ensure an equal say for each voter".
The number of MPs would be cut from 533 to 501 in England, from 40 to 29 in Wales, from 59 to 53 in Scotland and from 18 to 17 in Northern Ireland.
The newly-published draft Boundary Commission proposals for England and Wales follow those for Northern Ireland, which were published on 6 September, with plans for Scotland expected on 20 October.
Despite his criticism of the proposals, Mr Corbyn said he was confident of remaining as an MP if they come into force.
The Labour leader represents the Islington North constituency in London, and much of it is expected to form part of a new Finsbury Park and Stoke Newington seat.
Mr Osborne, meanwhile, sees his Tatton seat in Cheshire abolished, leaving him among three Conservative MPs left with just two constituencies.
Among the other proposals:
The East Yorkshire seat held by Brexit Secretary David Davis, Haltemprice and Howden, is facing major changes, as is ex-Lib Dem leader Nick Clegg's constituency of Sheffield Hallam.
The Stoke Central seat held by Labour's Tristram Hunt is among six seats being abolished in the West Midlands.
Every constituency in Wales is affected, with Labour leadership contender Owen Smith's Pontypridd constituency, to the north of Cardiff, split in two.
Two Conservatives, Stephen Crabb (Preseli Pembrokeshire) and Simon Hart (Carmarthen West and South Pembrokeshire) would have their constituencies merged.
they are determined to get rid of him one way or the other
