The Metropolitan Police Commissioner, Bernard Hogan-Howe, today vowed to stamp racism out of the force.
He told London Tonight that he would be an 'implacable enemy' to racists - and that he would root them out of the force. But he defended the 'vast majority' of his staff as professional and unprejudiced.
The Commissioner admitted that training in one of the most controversial police tactics - stop and search - could be improved, and that the force would focus on that in the coming year.
