Tory rebels and opposition MPs have defeated the government in the first stage of their attempt to pass a law designed to prevent a no-deal Brexit.
The Commons voted 328 to 301 to take control of the agenda, meaning they can bring forward a bill seeking to delay the UK’s exit date.
In response, Boris Johnson said he would bring forward a motion for an early general election.
Labour Party leader Jeremy Corbyn said Mr Johnson must get the Brexit delay bill that will be discussed on Wednesday passed before trying to call an election.
