Donald Trump in White House and Boris Johnson in Downing Street would be hair-raising

With the Trump Thatch on one side of the Atlantic and the Boris Barnet on the other, all talk of ‘heads’ of State is likely to mean something else entirely.
It would, of course, be comedy gold. A dystopian hell, mind, but anyone with a penchant for a bad pun (is there any other kind?) would be in seventh heaven: ‘Boris wins by a hair’; ‘Trump is hair apparent’; ‘Is this the final hairdown?’ Pause here for groans.
