I am grateful to my hon. Friend for giving way, and apologise for going back to the point that was first raised by my hon. Friend the Member for Crawley about the cost of foreign national offenders, because I can trump the figures that were given earlier. The National Audit Office estimated the cost of administering foreign national offenders in the UK for 2013-14, including police costs, Crown Prosecution Service costs, legal aid costs and prison costs, to be between £769 million and £1 billion a year. The most likely estimate was £850 million a year.
