The hon. Gentleman states that we have an “arbitrary” approach to detention; I strongly rebut that—we do not have such an approach. He should know that when anyone is detained, there must be a reasonable prospect of removal within a reasonable time. In recognising that improvements could nevertheless be made to our detention system, we commissioned the Shaw review, and as the hon. Gentleman may recall, I came to the House not so long ago to respond to the review and accepted many of its recommendations.
