1330 UPDATE: ITV London news has reported on this growing row today with our MP Andy Slaughter calling on the Mayor to suspend Mr Greenhalgh in view of the announcement by the IPCC.Mr Slaughter argued that since the allegations amount to serious criminal misconduct in public office it was no longer appropriate for Mr Greenhalgh to have responsibility for policing.

Coming so soon after his half-apology over allegations of sexual molestation of staff, the odds must be shortening on the first Deputy Mayor to walk the plank of Boris' new term. I suspect more than a few police officers may be enjoying the episode.
1530 UPDATE: The Conservatives have hit back as hard as they can this afternoon, with an impassioned piece on the Tory blog ConservativeHome. No author name is given for this article but it is likely to be penned by H&F Councillor Harry Phibbs, who partly edits the local government section of the site. And who has come to Mr Greenhalgh's aid before.
Mr Greenhalgh himself has issued the following comment:
"I am immensely proud of my record as Hammersmith & Fulham Council Leader. These baseless allegations are politically motivated. I refuse to be distracted from my important role as Deputy Mayor for Policing and Crime."
