Our Political Correspondent Simon Harris gets to the nub of today's row at City Hall.
The simple question in the police headcount row is this: How many extra officers will be on the streets in 2015? @itvlondon
Will it be 1,182 as claimed by Boris Johnson? Or will it be 56 as suspected by Labour? @itvlondon
Johnson: There will be an increase of 1,182 police officers in boroughs. @itvlondon
JM: "You have not enlightened us". BJ: "It is very difficult to enlighten someone who reuses to be enlightened". @itvlondon
McCartney says Labour has asked the UK Statistics Authority to investigate. @itvlondon
Johnson: The critical thing is the police are getting numbers out from the backroom. @itvlondon
Johnson to McCartney: I wasn't aware of the discrepancy and when we dug into it I think you were misinformed. @itvlondon
Johnson: I'm not accusing you of willful ignorance or willful misunderstanding...@itvlondon
Johnson: If there is a way of coming up with a new target for rape and sexual violence, then we shall look into it. @itvlondon
Labour's Joanne McCartney accuses the mayor of using a bogus headcount in his police and crime plan. @itvlondon
McCartney claims the number of police officers used in the public consultation is wrong by 1,100. @itvlondon
