One of the first things I announced when appointed as the Secretary of State for Justice was a £40 million extra investment to strengthen prison security, including £10 million for counter-drone measures such as netting and wire. I recently visited Woodhill prison to look at how we are tackling this growing threat and committed a further £35 million to install heavy-duty grilles on windows at 17 of our most high-risk prison sites.

My hon. Friend knows that, because of the war in Ukraine, drone technology is moving at pace. That is why, when I was in Ukraine in January, we announced that we are working with the UK defence innovation fund—an innovative fund—to set up an international business competition to ensure that the Prison Service keeps up at pace with moving technology. We are also working with our French and Italian colleagues, who are experiencing the same threat.

The hon. Gentleman is absolutely right. The director-general of the National Crime Agency has directed police chiefs to work with the Prison Service to jointly tackle the threat from criminal drones. We saw that recently in a large-scale joint operation that resulted in more than 200 arrests. He is absolutely right; that blocking technology is available to the system.
