The Parliamentary Under-Secretary of State for Justice (Jake Richards)

Prison security is a top priority. We constantly update our countermeasures to keep pace with criminals who try to undermine them. This year, the Government are investing over £40 million in physical security. That includes £10 million on anti-drone measures. Prisons also have X-ray body scanners, airport-style enhanced security and X-ray baggage scanners.
