I now just want to touch on the issue of rehabilitation, and we heard the Minister talk there about 90 percent of prisoners having drug and alcohol or mental health addiction needs. Under written question No. 3322, I have figures which have been released to me which show that in 2017-18, 4,075 people in prison received drug and alcohol rehabilitation programmes or were part of them. That dropped to 1,180 in the 2019-20 year—so about 25 percent of the 2017-18 year. That's a 75 percent drop—a massive drop—in the amount of people receiving drug and alcohol rehabilitation programmes. He's identified the problem of the number of people in prison needing assistance, but the number of people getting help is only a quarter. Why is that?
