WHAT exactly is the point of David Cameron?

This is not a rhetorical question. Really, what is the point?

This is a man who ran on an election platform promising that he wouldn’t be there next time round and who, although nominally the head of the Remain campaign, can’t string together a cogent argument to support his increasingly tenuous position as Prime Minister.

(In)famously shy of debates in the run up to the last general election, Cameron must have thought he was being given a penalty kick when handed the spotlight by Sky.

But, as many an English footballer does, he took his eye off the ball when it really mattered and fluffed things in spectacular style.

Even the highly dubious support of newly appointed London Mayor Sadiq Khan — who, as if he hadn’t had enough of being accused of sharing platforms with extremists, chose to do exactly the same thing again when he took the stage with Cameron — didn’t help.

The PM may have felt pretty cocky as he began the show, no doubt soothed by the fact that Sky has never knowingly given the Tories a rough ride over anything. It didn’t last long.

He may have been touched up like Widow Twanky on a two-for-one day at the beauty parlour, but that was the most fun he had from the hostile studio audience.

Even the usually tame Faisal Islam gave him a monstering before the audience had their go. When one of their number came out with: “I am an English literature student, I know waffle when I hear it,” it was surely one of the most amusingly ironic non-sequiturs of recent times.

She could, in fairness, have been talking about either side of the debate. Sadly for Dave, she wasn’t.
