IMO, the EU is the party trying to play hard-ball over this. You continue to believe what you want (as per normal), but all I have seen so far from the EU team is disingenuous, such as Juncker leaking/misleading after a PRIVATE meeting at Downing Street. The UK government has said it is willing to sort this out fast, but that is different to being dictated to.
As I said, Theresa May can, unilaterally, solve the future situation of EU citizens in the UK. This wouldn't involve any input from the EU. But she hasn't. And by declaring a totally unneeded election, and further delaying talks, it's pretty clear the government doesn't have speed at the forefront of its Brexit thinking. In fact we are now one year after the EU referendum and **** all has been discussed to date. Where on earth do you get this idea the UK wants to act fast?
