I join the Secretary of State and the shadow Secretary of State in their powerful words today in this House. Everybody is shocked and horrified at what happened in Londonderry just before the weekend. It has brought a palpable sense of real grief, shock and anger across the community at how a young lady who had so much to offer, Lyra McKee, was struck down in such circumstances. We had the appalling statement by those responsible that this was some kind of accident, as though it was okay to murder police officers. These are people—journalists, police officers and others—going about their proper business on behalf of us all, and they deserve all of our thanks and gratitude. Can the Secretary of State be assured that all of the political parties and all of the community, right across the board, are united in their absolute determination that we will move Northern Ireland forward and never return to the terrible types of incidents that we have seen on such a scale before?
