Whatever one feels about Boris Johnson (and almost any one who’s had any truck with the man has, if he’s honest, highly mixed views) today’s election is a spectacular triumph for him. On the day Andrew Scheer, the Canadian Tory leader, announced he would be stepping down, the UK Tory leader led his party to their biggest share of the vote in half-a-century and swiped seats held by Labour since 1935 – from Blythe Valley to Bishop Auckland. Both Scheer and Johnson are unprincipled opportunists, but the latter is a fighter who knows how to return the ball and swat it down the opposition’s gullet.
