I am most grateful to my hon. Friend for his pertinent intervention and question. He demonstrates not only his attention to detail and his determination to ensure that he represents his constituents here on a Friday, but that he can get straight to the nub of the issue. He is as concerned as I am about the cost to his constituents of any aspect of Government expenditure. The answer to his question is that if there are 10,500 foreign national offenders in our prisons, the estimated cost is something like £300 million a year. The Home Office figure for the cost of imprisoning a prisoner is something like £26,000.
