Police officers who are rude in public or work while unfit face being punished under a new code of ethics drawn up to improve the force's reputation.
The guidelines, written by The College of Policing, would punish officers who appeared for work under the influence of alcohol, and those who had sex or took drugs while on duty.
Officers will be urged to blow the whistle on colleagues of all ranks and failure to comply to regulations could lead to disciplinary action and even dismissal.
The College of Policing hope the guidelines will help to restore the public's faith in the police, after a series of corruption, race and behaviour while undercover scandals rocked constabularies across the UK.
The Home Secretary is understood to back the guidelines and they will go before parliament, although no date has yet been finalised.
