There is a meme doing the rounds already. The PM wrote F.Off next to Boris Johnson's name and some civil servant misunderstood. It would be funny if it wasn't serious.
I struggle to understand her rationale on this appointment. I don't dispute his intelligence, for all his cuddly appearance. But he is a maverick. At a time when most of the rest of the western world is already questioning our sanity in voting for Brexit, surely we need a steady pair of hands to help our relations with the rest of the world. Steady is not the same as bizarre.
I've come to two possible explanations. One is that she is appointing the most outrageous cabinet possible, prior to resigning abruptly as she leaves them (and us) to stew in the catastrophic outcome of the referendum. Alternatively, she has appointed him for a, say, three month period, so that the Americans can see what happens when you give power to a complete loon, realise the error of their Trumpish ways, and then she can sack him and put someone slightly less erratic in place.
I'm beginning to think that leaving the country will not be sufficient. I may have to investigate leaving the planet...
