Diane Abbott missed the second reading of the Brexit Bill last week
The Shadow Home Secretary – one of Jeremy Corbyn's key allies – missed the second reading of the Bill last week due to illness.
But she turned up to the Commons tonight to back the triggering of Article 50.
Speaking after the vote, she warned Brexit will be "quite disastrous" but insisted Labour would hold the Government to account.
She said: "The shadow cabinet agreed this week that we would vote for the third reading of triggering article 50 and I did that.
"I think that a Tory Brexit is going to be quite disastrous.
"I don't believe we've given a blank cheque, no. We're going to be holding them to account on the floor of the House."
Theresa May mocked Mrs Abbott during Prime Minister's Questions earlier today.
She said: "Perhaps members of the Labour Party are starting to realise that the only real headache is their leader."
Shadow Business Secretary Clive Lewis resigned from the frontbench to vote against triggering Article 50
He said: "When I became the MP for Norwich South, I promised my constituents I would be ‘Norwich’s voice in Westminster, not Westminster’s voice in Norwich’.
"I therefore cannot, in all good conscience, vote for something I believe will ultimately harm the city I have the honour to represent, love and call home."
Mr Corbyn said: "I would like to thank Clive for his work in the shadow cabinet, which has underlined what an asset he is to the Labour party and our movement.
"I wish Clive well and look forward to working with him in the future."
