The trial of nine men has started at London's Old Bailey which focuses on the sexual exploitation and corruption of vulnerable young girls in the Oxford area.
The allegations cover an eight-year period, during which it is alleged that the men systematically abused teenage girls, some as young as 11 at the time of the offences.
The joint operation between Thames Valley Police and Oxfordshire Social Services is called Operation Bullfinch.
The men are charged with 50 counts of rape, rape of a child, conspiracy to rape, sexual activity with a child, facilitating child prostitution and trafficking. It took 20 minutes to read the full list to the court. The men deny all the charges.
