So after all the noise, controversy and trips to the Supreme Court, the House of Commons voted 498-114 to give the Prime Minister the power to trigger Article 50. The next stages (committee, Lords, third reading, etc) will take a few more weeks.
In the meantime that means there's plenty of analysis to be done, as with the Trump petition. Chris Hanretty had a look at how MPs voted last night based on how their constituency voted and, not surprisingly, there's a pretty strong relationship between the two
As we know, there's also a very strong relationship between how the public view party leaders and how they vote. So last night's Polling Matters is interesting because its Opinium poll goes into detail about what people think about the Prime Minister and Leader of the Opposition.
As Keiran Pedley points out, the striking here is the size of the gap between the two, but the breadth of the measures across which it applies. May leads on all six questions (including "understands people like me", where her predecessor tended to trail) and has positive net ratings on five of them, Corbyn is net negative on all six.
Also on their agenda was Northern Ireland. The LucidTalk poll showed a reduced lead for the DUP as was widely expected, but the distribution of votes is likely to mean a clearer lead in terms of seats.
Today we get the Brexit white paper and three local by-elections, two of which are Labour-UKIP battleground of Rotherham, which some have their eye on in advance of the Stoke Westminster by-election in three weeks' time.
