Mr Speaker, may I associate myself and everyone in the House with your comments about PC Keith Palmer on this anniversary? May I also remind the House that yesterday marked 30 years since the IRA's Warrington bomb? My thoughts are with those who were affected by this atrocity, which caused the death of two young children, Tim Parry and Johnathan Ball, and injured 54 others. It is a reminder of the terrible cost of the troubles and of the vital importance of maintaining peace and improving political stability in Northern Ireland, and I am grateful to all those who continue to promote peace and reconciliation in our society. Last week, I visited the United States for the St Patrick's day celebrations, and I am keenly aware that that the eyes of the world will be on Northern Ireland in the month ahead as we prepare to mark the Belfast/Good Friday agreement's 25th anniversary. A host of events, big and small, civic, private and public, are being organised, many by Queen's University Belfast, to mark this important anniversary.

I agree with my hon. Friend that this historic moment is an achievement not just for Northern Ireland but for the entire United Kingdom. We have an educational initiative that is going to offer young people across the United Kingdom an opportunity to engage with the anniversary by learning about the journey to the agreement and its crucial role in providing peace and prosperity in Northern Ireland.

All three strands of the agreement are vital, and all need to be working, but the hon. Gentleman is completely right to say that strand 2 and the council are very important as we move forward from this point. Twenty-five years of peace and stability have flowed from the signing of the Belfast/Good Friday agreement, and I would like to think, as we look forward, that we will have not just peace and stability but prosperity for the next 25 years.

We have a number of big visitors coming to Northern Ireland to mark this important anniversary, and I know that the PSNI is remarkably well organised in preparing for this. Of course the Government will happily support the PSNI in its endeavours.

First, I pay tribute to all the officers in the Police Service of Northern Ireland for all the work they do across communities, and to the Chief Constable. He has brought in community policing, of which most of us will be cognisant in our own areas but which is almost new in Northern Ireland. As the hon. Gentleman knows, policing is devolved to the Executive. I am well aware of the Chief Constable's asks in this area, and I am talking to him about them.
