JEREMY CORBYN

His Dumbledore approach of looking calm and kindly but also full of all the “right” kind of values would be a magnificent selling point to a younger audience in a different climate.

The Labour leader’s body language is a world away from Trump but the effect is similar. His apparent lack of spin, gloss and non-verbal training could be appealing in itself.

Congruence is seductive in a culture of sound and sight-bites but now even Mr Corbyn seems to be succumbing to the sheep dip of leadership appearance and it could be his weakness as it was for the over-choreographed Ed Miliband.

His current vibe seems to be to adopt a pose of relaxed calm and indifference. During TV interviews he has been leaning back in his seat, legs stretched out. A great look for good times but maybe not so reassuring if you feel the UK is in danger of sinking.

His normal pose is more alert and upright but with an uneasy smile, which means he can shift from calm to passionate/angry quite naturally.

This overdone air of relaxation suggests he is close to boiling point.

Mr Corbyn’s best speaking and debating style is quasi-religious, delivering his values straight into the distance and not engaging in the petty squabbles on the ground.

VERDICT: He used to be a master-class in anti-spin but now he’s joined in the game with everyone else when it’s not really his forte. Can you see him on the sofa with his wife talking about wardrobe space? Great when he gets into his stride in a debate and starts tub-thumping but will that happen?
