In full: Theresa May interview on Today

Theresa May said she was talking to colleagues about their concerns over the Northern Ireland "backstop" ahead of a crucial vote on her EU withdrawal agreement.

She suggested MPs could be "given a role" in deciding whether to activate the backstop, which is designed to stop the return of a physical border.

But she told the BBC there could be no deal with the EU without a backstop, and again ruled out a further referendum.
