Will Boris be haunted by the time he compared Hillary Clinton to a 'sadistic nurse in a mental hospital'?

When Boris Johnson described Hillary Clinton as 'like a sadistic nurse in a mental hospital' he probably never imagined they would meet.

But tomorrow London's mayor will come face to face with the woman regarded as the Democrats front-runner for the White House.

It could be an awkward moment for a man who often resorts to flowery prose to insult his political opponents.

Boris Johnson wants to talk to Senator Clinton about Iraq, Syria, the terror threat from Islamic State and Europe.

But their meeting could be haunted by his less-than flattering comments in a newspaper column in 2007.

The mayor told ITV News today he hoped she would not take offence.
