A senior policewoman could face getting the sack after an alleged row with a fellow colleague over who had the better shaped breasts during a drunken night out.

Rebekah Sutcliffe, Assistant Chief Constable of Greater Manchester Police, criticized Superintendent Sarah Jackson for "pandering to men" by having cosmetic surgery and allegedly bared her own breasts to show that they were better and more attractive.

Sutcliffe could lose her job if she is found guilty for gross misconduct by a public disciplinary hearing later this year. Jackson has been cleared of any alleged charge.

A spokesman from Greater Manchester Police said: "We can confirm that following an investigation by Durham Constabulary the Deputy Chief Constable has determined that a senior officer has a case to answer for gross misconduct and will face a disciplinary hearing."

She could either be hit with sanctions ranging from management advice to dismissal.

The alleged row, broken by the Mail On Sunday, occurred while they both attended a Senior Women in Policing conference at the Manchester Hilton that was aimed at enhancing "profile and perception" of female officers. Witnesses apparently reported Sutcliffe, 47 and Jackson to bosses immediately after the event.

It is not the first time Sutcliffe has been investigated. Two years she was probed for failing to declare her relationship with Detective Superintendent Paul Rumney, who then was in charge of the force's Professional Standards Branch while she sat on a disciplinary panel.

She also was given 'suitable advice' by a senior officer in 2010 after reportedly trying to gatecrash a Labour Party conference event.
