The BBC Europe Editor was talking to colleague and Political Editor Laura Kuenssberg about the Brexit extension agreed in the crunch EU summit. Dr Adler said: “Part of the fudge was, you know how the idea is that the 27 EU leaders all have their own veto on the extension. In the end, it does come down to the big powers because you had Macron one side saying short extension or bust and Merkel saying long extension lets give them as much time as possible and they have met somewhere in the middle.”
Mrs Kuenssberg said: “Isn’t that amazing, are you suggesting that actually big EU decisions are made by France and Germany between themselves managing to find accommodation?”
Dr Adler laughed and added: “Well, sometimes, it does not always work that way but from a historical European point of view you can see why Angela Merkel and Donald Tusk from the Polish and the East German perspective wanted to play this long.
“In their experience in their lifetime if you are patient things change and those are two EU leaders who would love things to change in the UK.
“For the UK either to change its mind or for a much softer Brexit to be on the table.
“They are not as thrilled, is October really long enough to give that space were it wanted or needed.”
The UK is heading for a Halloween Brexit after the remaining 27 EU nations offered Theresa May a further six months to ratify or rethink her withdrawal deal.
The second extension to the Brexit process – initially intended to conclude on March 29 – definitively stopped the clock on a no-deal withdrawal on Friday with less than 48 hours to go.
In an early-hours press conference, European Council president Donald Tusk did not rule out further extensions beyond October.
And he sent a message to the UK: “This extension is as flexible as I expected, and a little bit shorter than I expected, but it’s still enough to find the best possible solution.
“Please do not waste this time.”
Addressing the press shortly before 2am, Mrs May said that she still wanted the UK to leave the EU “as soon as possible”.
Brexit Minister Kwasi Kwarteng told BBC Radio 4’s Today programme: “It is not a secret that we have had a difficult time in trying to get the deal through the House of Commons.
“Parliament is in gridlock at the moment and I think that we have got the time, hopefully, to get the deal through.
“But, it’s been challenging.
“I think that the extension is long enough to get a deal through.”
