Criminal Justice and Immigration Bill

May I remind the right hon. Gentleman that I was the Prisons Minister at the time of the Wandsworth strike? I therefore approach this matter as one who had to deal with a strike by prison officers. I agree with the analogy made between prison officers and police officers, but I fail to see why we should ever have contemplated relying on a voluntary agreement with the POA. Either now or in the future, there needs to be a statutory prohibition in force that is in no way the subject of a voluntary agreement.
