Forget the policies: which politician's hair would you rank as the most unforgettable?

It never once looked brushed, even at the big state occasions. Some swear he messes it up on purpose before the cameras roll.

Solid, sculpted and sprayed into place. It could have survived a gale on the Downing Street steps.

Big, swept-back and very 1980s. It looked more like a rock star's hair than a minister's.

Neat, grey and very much part of the brand. It goes with a flat cap and a jar of homemade jam.

Combed flat with a perfect parting, every single day. Your nan would approve.
