One of London Mayor Ken Livingstone's key aides will not be facing any police investigation as there is no evidence of criminal activity, Scotland Yard have said.

Crime and equality adviser Lee Jasper has been at the centre of a string of allegations made by the Evening Standard regarding funding irregularities at community projects.

The newspaper claimed hundreds of thousands of pounds had been paid to the projects, with little work being carried out.

Last week Mr Jasper was asked by the mayor to refer these to police in a bid to clear his name.

However, a Met police spokesman said allegations of misconduct, where there is no evidence of a crime, were not a matter for the police.

He confirmed the met was investigating six allegations of fraud that had been referred to police in connection with six organisations that had received public funding.

He said: "In addition we have received a request asking us to consider the conduct of one individual and his involvement with these organisations.

"To date there have been no criminal allegations reported to us in connection with this individual, but as with anyone should concerns arise out of the fraud investigation, or subsequent criminal allegations be reported to us these will be considered and appropriate action taken.

"However matters of alleged misconduct that are not supported by evidence of criminal wrongdoing are not a matter for the police."

After being suspended as an officer for the Greater London Authority last week, Mr Jasper also stepped down from his role as chairman of the Trident Independent Advisory Group on Monday.

Writing to members of the group, he said the media's "politically-motivated racist smear campaign" had forced his resignation.
