29 March isn't approaching any slower. The EU is universally and loudly saying there will be no further deals. They are ticked off at the Brits. Article 50 probably won't be extended because there has to be a reason for Europe to grant the extension and the UK is so fooked right now there is nothing they can offer. Even if they were willing, the EU won't be able to negotiate until the fall because of elections. A second vote on Brexit could be just as divisive as the first and there won't be a general election in the UK until next decade. Even if May was willing to resign (which she inexplicably isn't) there is no one to become PM in her stead. The Tories don't love her but there is no one else they can unite around.
We're flying into Edinburgh on 11 April. Hopefully we don't land in the midst of chaos and civil unrest...but if the British Pound wants to fall even more against the $ that would be cool.
