Max Hastings is a former editor of the Daily Telegraph, and was Boris Johnson's employer for several years.

Readers might be interested in his view of Johnson's personality.

"Boris is a gold medal egomaniac...His chaotic public persona is not an act - he is, indeed, manically disorganised about everything except his own image management. He is also far more ruthless, and frankly nastier, figure than the public appreciates...He is not a man to believe in, to trust or respect, save as a superlative exhibitionist. He is bereft of judgement, loyalty and discretion. Only in the star-crazed, frivolous Britain of the 21st century could such a man have risen so high, and he is utterly unfit to go higher still"
