A prison nurse who had an affair with a convicted rapist at one of Britain's highest security jails will be sentenced today.
Karen Cosford, 47, had sex with inmate Brian McBride, who was serving a life sentence at Wakefield Prison.
She sent the prisoner intimate text messages to his smuggled mobile phone and wrote him a love letter which was found hidden in a jar of sugar.
Cosford performed a sex act on McBride while she was on duty as two colleagues - Carolyn Falloon and Jacqueline Flynn - guarded his cell.
On another occasion, Falloon caught her having sex with the inmate in the medical unit, but failed to report it.
Cosford, of Normanton, West Yorkshire, who worked in the jail's medical centre, was found guilty of misconduct in a public office last week after a four-week trial at Leeds Crown Court.
She was also found guilty of failing to tell prison authorities that McBride had a mobile phone, and supplying him with mobile top-up vouchers.
Falloon, 50, of Wakefield, and Flynn, 46, from Pontefract, were found guilty of failing to report the relationship and not reporting McBride's mobile phone. Falloon was also found guilty of supplying McBride with mobile top-ups.
Health care officer Kevin Wilson, 56, of Normanton, earlier pleaded guilty to failing to notify authorities of Cosford's relationship, failing to tell authorities McBride had a mobile phone and supplying McBride with a sim card.
All four will be sentenced at Bradford Crown Court this afternoon.
