Brougham is the oldest of 13 men charged with sexual offences against the woman. The men were allegedly invited into her home, in the Stockport area of Greater Manchester, to abuse her by her husband.
The husband, in his sixties, has already admitted 62 offences against his wife, including rape, and has given a witness statement detailing what he says happened.
The case is being reported as breaking news, with further details expected to emerge. Brougham's sentencing is yet to come before the court.
