The United Kingdom government says it will push ahead with efforts to pass its Brexit deal, despite a major setback to its plans.

Boris Johnson had to ask the EU for an extension to the UK’s 31 October exit date after MPs backed a move to delay approval of the deal on Saturday.

But Foreign Secretary Dominic Raab said he was confident enough MPs would back the deal next week, and Brexit would still happen by the deadline.

Labour, however, has said it will back moves to put the deal to a referendum.

No 10 said the Boris Johnson sent “Parliament’s letter” to Brussels – unsigned – and accompanied it with a second letter – which was signed – explaining why he believed a delay would be a mistake.

The government has vowed to press ahead with the legislation – the Withdrawal Agreement Bill (WAB) – to implement the Brexit deal next week.
