Greenhalgh and Jenny Jones argue about police numbers. She calls him "offensive" and tells him to "mind your manners" @itvlondon
One of Boris Johnson's deputy mayors has been involved in a heated exchange over police numbers.
Opposition politicians cast doubt on the mayor's pledge toput an extra 1,200 police officers on the streets.
During a debate at City hall, the Deputy Mayor for Policing Stephen Greenhalgh clashed with London Assembly member Jenny Jones.
Mr Greenhalgh: "Your line of questioning indicates your lack of understanding of the figures we are presenting."
Ms Jones: "Well I think that your answer is actually a complete fudge."
Mr Greenhalgh: "You clearly don't understand the figures."
Ms Jones: "Mr Greenhalgh you're very offensive and I'd like to say that you really ought to perhaps mind your manners."
