As it happened: MPs back Johnson's Brexit bill - BBC News
MPs vote by 358 to 234 to back the prime minister's plan for the UK to leave the EU on 31 January - a majority of 124.
It is going to be tricky - though not impossible - for Clive Lewis (pictured) and some other candidates to be the next Labour leader to get on to the ballot in the first place.

Under former leader Ed Miliband's reforms, MPs were the gatekeepers in the process - the sole nominees of candidates, with no role for the unions nor the grassroots.

But under Mr Corbyn, two more criteria were added.

A candidate now also has to be nominated by "5% of affiliates" - translated, this means basically two of the dozen affiliated unions, or one big union and a "socialist society" such as the Fabians.

If this proves impossible then 5% of constituency parties would have to nominate - that is, more than 30 local groups.

Mr Lewis has told me that, so far, he has no union nominations, but would expect some left-led constituencies to come behind him if they want a debate.

His championing of Remain from the left and not the Blairite/centrist wing of the party endeared him to many grassroots activists.

But his difficulty is he will be fishing in the same waters as Rebecca Long-Bailey, another left-winger who is more likely to get union support.
