The identities of 13 men charged alongside a man accused of drugging and raping his wife can be revealed after reporting restrictions were lifted.

The main defendant in the case is due to go on trial in September. He stands accused of drugging and sexually assaulting his wife over a period of 20 years and conspiring with other men to engage in abuse.

The identity of the man, who is in his 60s and from the Stockport area of Greater Manchester, cannot be revealed in order to protect his wife’s anonymity.

He has pleaded guilty to 15 charges – five rapes, three sexual assaults, six assaults by penetration and one count of sharing intimate images without consent – and denies 33 other charges.

His co-defendants, who range in age from 28 to 73, face charges including conspiracy to rape and conspiracy to assault by penetration.

During a series of preliminary hearings at Manchester’s Minshull Street crown court, some of the men, who include a paramedic, a football coach and a taxi driver, have been dressed smartly in shirts and ties while others have arrived at court wearing tracksuits and slouched in the dock.
