There are many ways to deal with this problem, letting murderers and rapists out early is the most stupid possible solution. Who cares if prisons are overcrowded? The Bangkok Hilton has communal cells that can accommodate 40-50 people. Is it comfortable for the inhabitants? Probably not. Is it avoidable? Yes - by not committing crimes. Knock a few walls down between 1 or 2 person cells and turn them into 20-30 person cells. Easy. Deporting the 11,000 foreign criminals would free up 11,000 spaces. Foreign aid and visas can be cancelled from countries that refuse to take them back. Trumps government managed to build detention centers for illegal immigrants in about 8 days. The UK has 2 months to do something like this. To pretend the only solution to not enough prison spaces is to let criminals out early is utterly moronic.
