Five extra Labour MPs rebelled at the third reading of the government's Article 50 Bill, but they weren't enough to stop the House of Commons overwhelmingly voting in favour of giving Theresa May the power to trigger Article 50.
Geraint Davies, Kate Green, Clive Lewis (who resigned from the frontbench today), Alison McGovern and Chi Onwurah voted against the government.
Labour whips Vicky Foxcroft, Thangam Debbonaire and Jeff Smith all voted against the strict three-line whip imposed by leader Jeremy Corbyn too. But shadow home secretary Diane Abbott voted with the government, after much speculation over which way she'd vote.
Conservative Ken Clarke was the only rebel to his party.
