Prime Minister Boris Johnson faces a new battle in the Commons after his first vote as PM saw him lose to rebel Tories and opposition MPs who object to a no-deal Brexit.
The Commons voted 328 to 301 to take control of the agenda, allowing them to bring a bill requesting a Brexit delay.
The PM said he would call for a general election if he was forced to request an extension to the October 31, deadline.
MPs’ will now vote on the Brexit delay bill. If it passes, the vote on whether to hold an election will follow.
Jeremy Corbyn said the bill needed to be passed to take the no-deal option completely “off the table” before his party would support the call for a general election.
Under the Fixed Term Parliaments Act, a prime minister must have the backing of at least two-thirds of MPs before a general election can be called outside of the fixed five-year terms.
Downing Street said the 21 Tory MPs’ who rebelled in Tuesday’s vote would have the whip removed, effectively expelling them from the parliamentary party and meaning they could not stand as Conservative candidates in the election.
The rebels include several senior Conservatives including ex-chancellor Ken Clarke – a Commons veteran of nearly five decades – who said he did not recognise his party anymore.
“It’s the Brexit Party, rebadged,” he told BBC Two’s Newsnight programme.
Also among the other jettisoned rebels are Philip Hammond who – until July 24, – served as chancellor, former justice secretary David Gauke, Winston Churchill’s grandson Sir Nicholas Soames, and Rory Stewart, who recently stood against Boris Johnson to be the party leader.
Sir Nicholas said he would end his parliamentary career if a snap general election was held.
He said his decision to rebel was not taken “lightly”, but he felt strongly about avoiding a no-deal.
He added: “The fact is I’m satisfied that [the prime minister] himself wants a deal, but the deal he wants is not available.”
Hours before the vote on Tuesday, the government had already lost its working majority when Tory MP Phillip Lee defected to the Liberal Democrats.
After Tuesday’s drama, another momentous day is expected in Parliament.
Meanwhile in Scotland, a judge is due to announce his decision on whether the prime minister’s planned suspension of Parliament is legal.
