But on the bright side (for us in the rest of EU) it's also more likely to result in a "softer" brexit, if the election result is seen as a vote against May's Conservative plan.
That said, whoever replaces May - once she has been eaten by the Tory backbenchers - is likely to have been an original Brexit backer, which May was not. For example Boris Johnson. So it's all very uncertain at this point.
Edit: Was unsure about the exact date of negotiations - they were set to start on june 19th but it's uncertain if it can now.
Someone actually created a throwaway account to deliver a salty (now removed) comment that I should shut up if I didn't know what I was talking about - referring to "I believe.." in my original comment. Otherwise this would "Turn into reddit".
Someone is having a bad morning.
