On Wednesday MPs voted to allow Theresa May's government to trigger Article 50, and start Brexit.
Labour leader Jeremy Corbyn looked like he was (again) facing a frontbench rebellion after ordering his MPs to obey a three-line whip and vote with the government. In the end, 52 Labour MPs rebelled against Corbyn’s orders to vote for Article 50, and shadow cabinet member Clive Lewis resigned over it.
Following the vote, Corbyn tweeted: "Real fight starts now."
Which puzzled some people who thought he could have done a bit more earlier in proceedings.
Still, everybody is looking forward to the real fight starting.
Because absolutely nothing else can possibly go wrong.
This is not a fair comparison to make, obviously.
This is going to be a good fight.
The Labour party will remain unified and strong.
"Real fight starts now", eh?
