@Walter Hinteler,
The U's government is heading full steam ahead for a hard Brexit on 31 October - at least if you believe British media reports. According to the BBC, Downing Street has told EU partners that only substantial changes to Theresa May's exit agreement could prevent a no deal - which the EU continues to reject. And according to the Guardian, Boris Johnson has already signalled to the EU that he doesn't want any more negotiations. According to the Daily Telegraph, Johnson's special adviser Dominic Cummings told parliamentarians that they couldn't stop a no deal. For even if Johnson were to be overthrown in a vote of no confidence in September after the end of the parliamentary holidays, Johnson would remain in office until new elections - and he could delay them until after the departure date.
I still hope Johnson is just bluffing, but we should not rule out the possibility that he is putting his threats into practice.
