A top political interviewer was left banging his head on the table in despair after Sir Michael Fallon refused to admit Boris Johnson's words on terrorism.

Robert Peston confronted the Defence Secretary over laying into Jeremy Corbyn for linking the growth of terrorism with foreign interventions abroad.

It comes just days after Sir Michael was skewered on Channel 4 new for criticising a quote about terrorism - before being told it came from the Foreign Secretary.

Appearing on ITV's Peston on Sunday, Sir Michael insisted that Mr Corbyn had attempted to draw links between British foreign policy and terror attacks, to which Peston said: 'He said no such thing.'

Sir Michael replied: 'He did. I've got his words here. He said foreign policy has been increasing the threat to this country.

'He said that in his speech on Friday and this is nonsense.'Peston intervened, saying: 'This is not the same thing as saying the terrorist attacks are our fault.

'Boris Johnson, the Foreign Secretary, made exactly the same point a few years ago.'

Sir Michael insisted that Mr Johnson had not, but the increasingly exasperated interviewer said: 'He did, he made exactly the same point, I've got his words.

Pointing to his papers, the Defence Secretary shot back: 'I've got his words here, let me read them to you. He said the Iraq war did not create the problem of murderous Islamic fundamentalism.

'Peston intervened and said: 'He said "those who argued that the attack on Iraq and the way we got rid of Saddam without rebuilding Iraq, those people who said that would increase the threat of terrorism, they had a point".

'Those were his exact words.'

As Sir Michael tried to object, the interviewer pointed to his papers and said: 'Do you want me to show you the article? Michael don't argue with me about it, I've got it.'

As the credits rolled at the end of the interview, Peston could be seen banging his head on the desk in despair.
