My hon. Friend is right to point that out. Everyone wants a fair and compassionate system, but they also want that system to be robust and for the rules to be enforced. If someone tries to take advantage of the system, clearly that must be pursued. I referred in my statement to Operation Fugal, and I understand that one reason why it was begun was that a pattern of fraud was recognised by Home Office officials. When many of those cases were investigated by the police, the Crown Prosecution Service brought charges against individuals. I will not talk about those particular cases, for obvious reasons, but that helps to demonstrate that when people are engaging in wrongdoing, we will pursue that.
