As I predicted The UK got its extension to the Article 50 deadline, and as expected it was short.
The 29th March leaving date has been pushed back to 12th April but this is a mere two-week extension and in line with my view that the UK would get something tokenistic. The 29th was an almost-arbitary date picked by the UK so the rest of the EU had no special attachment to it, and it feels more like giving enough rope rather than extra breathing space. The 12th on the other hand is notable because it is the deadline by when the UK has to decide whether to participate in the 2019 Euro-elections.
Such participation was always going to be the major condition of anything other than the shortest of extensions. If participation is a definite “No” then there is clearly no appetite for the UK to hang around. Theoretical Remainer dreams such as unilateral revocation of Article 50 become even more contrived, so the only realistic reason to stay at all is technocratic stuff related to deal implementation.
There is PR to the presentation, but it has come down to the EU having to force a decision from the UK.
