Let’s try a thought experiment, shall we? If a senior adviser to my old boss, Boris Johnson, had celebrated John Smith’s heart attack, mocked Gordon Brown for talking about his dead son and referred to senior members of the Labour party as ‘scum’, how long do you think that person would have kept their job? Thankfully, however, this particular mini-Trump, the former reality TV star Amy Lamé, was appointed (as London’s ‘night czar’) by a Labour mayor, and her -targets were all Tories, so it’s fine.
