A top law firm is to challenge the UK government over the Brexit decision.

This follows one of the two mechanisms outlined before. Essentially that the Prime Minister does not have the authority to initiate Article 50 without a debate and vote in Parliment. This could get very interesting and potentially make life awkward for MPs. If it does go to a vote in Parliment, I suspect they will come under intense pressure from their constituents to vote both for Leave and for Remain. So they'll have to choose one or the other. And unlike a referendum, the way an MP votes on any particular issue is a matter of public record. Their constituents will know which way they voted.

Even in a constituency with a slight majority for Leave, there will be more than enough voters in the Remain camp to bring down an MP at the next election. And vice-versa of course. In a sense they will be caught between a rock and a hard place.

Even the government has much to risk in this process.

  • If they vote to Leave in line with the referendum they'll further alienate the Remain camp as they'll be seen as having thrown away an opportunity to reverse a deeply unpopular choice.
  • If they vote to Remain they'll be strung up by the Leave campaign as being undemocratic by ignoring the referendum.

Politically speaking, for next few months, there will be a lot of blood in the water over Brexit. And I suspect Gove and Johnson are not the last political careers we'll see ruined.
