David Cameron once chastised him for dressing so shabbily the then Prime Minister’s mother would order him to “put on a proper suit [and] do up his tie”.

But now, wearing a perfectly-fitted Marks and Spencer two-piece with a bold, brilliantly red tie, Jeremy Corbyn’s a GQ cover star.

It’s a transformation befitting the tumult unleashed upon British politics since Cameron mocked his opponent during PMQs in February 2016.

At the time, the topic of controversy was whether or not Corbyn had sung the national anthem with appropriate gusto.

Little wonder then that January’s cover, previewed on Thursday ahead of its general release, is seen by many as symbolic of just how much things have changed.

I met Jeremy Corbyn twice before it was cool, and never did I imagine him as the sort of bloke who’d end up on the front of GQ ? There’s hope for us all. https://t.co/HmqEIfdgn8

Clever from Corbyn to appear in GQ, but wearing an M&S suit. Photo also shows how much smarter Corbyn looks now than in 2015 https://t.co/Dj41QqvbZg

And, of course, not everyone was impressed with Corbyn’s apparent transformation. Some went as far as claiming a skilful hand was at play.
