• As a Briton the idea of any of the last three PMs in a presidential system is really scary in my opinion. It’s easier to depose a leader that’s failing badly in the UK which is a good thing, I think the problem is the fact too much of our actual machinery of government is based on centuries-old gentleman’s agreements which is fine up until you get a complete stranger to honour like Boris Johnson who will abuse our fairly fluid constitutional arrangements to cling onto power like a tick.

    In theory the monarch is supposed to be the last line of defence against a genuinely scary and out of control government that Parliament can’t reign in but we saw how well that worked over the last three years.
