Rebekah Sutcliffe, assistant chief constable of Greater Manchester Police, faces the sack as investigations continue.

Witnesses say Ms Sutcliffe was arguing with Superintendent Sarah Jackson over which officer had more attractive breasts, and exposed her own breasts in a bid to win the argument.

Ms Sutcliffe allegedly also claimed Ms Jackson, her junior, was “pandering to men” by undergoing cosmetic surgery.

Ms Jackson has already been told she faces no further action.

A spokesperson for GMP told the Mail on Sunday: “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.”
