Mobile phones and SIM cards have been found in cells at Bristol Prison an average of three times a month, Government figures have revealed.
Officers discovered 18 handsets and 14 SIM cards had been smuggled into the Category B prison in Horfield over the last financial year.
That translates to one in 19 inmates having the potential to make uncontrolled contact with the outside world.
But as the figures only relate to phones and cards found by the authorities, the true scale of the problem could be far greater.
The Liberal Democrats used the records, which were released in Parliament, to claim that prisons were out of control.
