Prime Minister Theresa May making the speech in central London.
Prime Minister Theresa May has said there is “one last chance” to help MPs deliver the result of the 2016 referendum, as she offered a “new Brexit deal”.
Mrs May said: “The new Brexit deal will set out in law that the House of Commons would approve the UK’s objectives for the negotiations on our future relations with the EU.
“And they will approve the treaties governing that relationship before the Government signs them.”
She said the new Brexit deal will seek to conclude alternative arrangements for the Irish backstop by December 2020.
At a speech in Westminster, she said: “Although it’s not possible for (alternative arrangements) to replace the backstop in the Withdrawal Agreement, we can start the work now to ensure they are a viable alternative.
“So as part of the new Brexit deal we will place the Government under a legal obligation to seek to conclude alternative arrangements by December 2020 so that we can avoid any need for the backstop coming into force.”
The Prime Minister said her Withdrawal Agreement Bill will include a vote on whether to hold a second referendum.
