We have invested in improving security through the use of body searches and metal-detecting technology in every prison. We are also trialling new X-ray body scanners to reveal more hidden items. We have invested £3 million to establish national and regional intelligence units in Her Majesty’s Prison and Probation Service which, with prisons, probation and law enforcement partners, are building intelligence about the highest-risk offenders.
I thank my hon. Friend for his question and his suggestion. We are taking decisive steps to tackle drones bringing contraband into prisons. Under Operation Trenton, Prison Service and police investigators intercept drones and track down the criminals behind them. There have been at least 32 convictions to date, with those sentenced serving in total more than 100 years in prison.
