One of the reasons I thought Macron came across well is that he made some relevant, interesting, insightful comments - at least when Marr was not interrupting him. I wanted to (did actually) yell at the screen, 'shut up, Marr', because Macron was saying something helpful, but Marr closed him down.
The difference (IMHO) is that UK politicians are too afraid of the Mail or Sun taking umbrage at what they say. So their media advisors recommend waffling about Party politics, or some obscure but irrelevant factoid, and so the Interviewer interrupts and we get into a ridiculous non-interview.
Macron engaged with Marr; he answered the questions; he set out his points and I felt I learned something from the discussion.
It is so rare to have that feeling after an interview with a UK politician. I get the feeling it is all about scoring cheap points against the other party.
