Boris Johnson has said he will press on “undaunted” with his Brexit strategy despite MPs backing the principle of a further delay to the process.
The PM vowed to introduce legislation needed to implement his “excellent” agreement in Parliament next week.
But he will have to ask the EU for an extension beyond 31 October after MPs backed a motion designed to rule out a no-deal exit by 322 votes to 306.
The EU said it was up to the UK to “inform it of the next steps”.
Ministers have signalled a vote on the PM’s revised Brexit agreement could now take place on Monday, depending on what the Speaker decides.
Today is an unusual day in Parliament. For the first time since 1982 MPs will sit in the @HouseofCommons on a Saturday, dubbed #SuperSaturday.
They’ll be debating and voting on Prime Minister @BorisJohnson’s Brexit deal ahead of the 31st October deadline to leave the EU. pic.twitter.com/ePGDyDs16F
