Sir Julian Lewis: While I agree with virtually everything the Secretary of State said in his opening response, I really am baffled by his refusal to share with the House a piece of simple information. Did this person come legally into this country and have a five-year visa because he came legally, or was he given the visa after entering the country illegally? The information will come out sooner or later, and we have learned from similar terrible incidents that the longer it is withheld, the worse the rumour mill goes into action.

[The Secretary of State for Northern Ireland (Hilary Benn): I understand the right hon. Gentleman’s last point, but it is very important in these circumstances to be absolutely sure about the facts before they are released. The proper vehicle for doing that is the PSNI [Police Service of Northern Ireland] being in touch with the Home Office, which is what has been happening this morning. As the right hon. Gentleman may be aware, the police originally said they believed the perpetrator to be of one nationality, but it may well turn out that he is in fact of another nationality. That demonstrates the point I am trying to put to the House: it is important that the police lead on that so that the full facts can come out, and then they can be made available to the House and to the country.]
