David Cameron has been heckled by someone purporting to be an SNP supporter during a speech in outer London.

In a short video clip of the incident a man with a Scottish accent can be heard to shout “come on SNP” and other inaudible comments.

Reporters on the scene who witnessed the full incident said the man had claimed the PM was “racist against Scottish people”.

A photo of the heckler appears to show him being held back by security.

The incident took place during a speech by Mr Cameron at Squires Garden Centre in Twickenham.

David Cameron used the speech to warn against a Labour-Lib Dem coalition.

“If you vote Liberal Democrat you don’t know what you are going to get. They are just as likely to support Ed Miliband and the SNP as they are the Conservatives,” he told his audience.

Yesterday SNP leader Nicola Sturgeon condemned “disgraceful” protests against Scottish Labour leader Jim Murphy.

The Westminster politician had had a speech drowned out by demonstrators playing loud music and chanting “red Tories out”.
