A shadow minister has quit after Jeremy Corbyn said that that he will force his front-bench team to vote in favour of triggering Brexit.

Tulip Siddiq, the shadow early years minister, said that because the "vast majority" of her constituents voted to stay in the European Union she cannot back triggering Article 50.

Mr Corbyn is now facing the prospect of two other shadow ministers resigning after vowing to impose a three-line whip on Labour MPs.

Ms Siddiq said in her letter to Mr Corbyn: "The vast majority of my constituents voted last year to remain in the European Union, as did I. On the announcement of the 3-line whip on the Article 50 vote I therefore feel I have no choice but to resign from my front bench role as shadow minister for easly years.

"I do not support the triggering of Article 50 and cannot reconcile myself to the front bench position."

It came as the Goverment warned politicians that they must "respect" the EU referendum result as it published its long-awaited bill that will give Theresa May the power to trigger Brexit.

David Davis, the Secretary of State for Exiting the European Union, said that he hopes Parliament will "pass the legislation quickly" as he tabled the 137 word bill in the Commons.
