Prince Charles honours fallen police at Cardiff memorial 29 September 2013 Last updated at 08:57 Prince Charles is leading the congregation at a memorial service in Cardiff for police officers killed on duty. Home Secretary Theresa May and First Minister Carwyn Jones will also join officers and their families at Sunday's service at St David's Hall. The first minister said the officers' sacrifice "is not forgotten." The prince is patron of the National Police Memorial Day service, which Wales is hosting for the second time. The event moves around the countries of the UK each year and was last held in Cardiff in 2009. Mr Jones, who is attending with Welsh local government minister Lesley Griffiths, said: "It is a privilege to host the 10th annual memorial service in Wales again this year. The police service makes an immeasurable contribution to our society for which we are all very grateful. Sadly, each year police officers continue to give their lives so that we can all live in peace End Quote Sgt Joe Holness QPM National Police Memorial Day founder Sadly, each year police officers give their lives making sure that we can all live in safety. The memorial service is an opportunity for us all to remember those officers and to ensure that their relatives, friends and colleagues know their sacrifice is not forgotten. National Police Memorial Day was founded in 2004 by Sgt Joe Holness QPM. He said: "Sadly, each year police officers continue to give their lives so that we can all live in peace. Yet police officers continue to run to danger for the sake of others and they continue to serve their country with pride and the utmost valour, knowing all too well the risks involved. Among those who will be remembered at this year's service are Metropolitan Police officer PC Andrew Duncan, 47, who was killed in a suspected hit-and-run collision just a week ago. Home Secretary Theresa May said: "The tragic death of PC Andrew Duncan brings home the importance of National Police Memorial Day, when we come together to remember the debt of gratitude we owe to policemen and women across the country who put themselves in harm's way to protect us. PC Duncan gave more than 20 years' service to the people of London and was described by colleagues in the Metropolitan Police as both courageous and hard working. Greater Manchester PCs Nicola Hughes and Fiona Bone, who were killed in a gun and grenade attack last September, will also be remembered at the service. Ms Hughes's stepmother Natalie Hughes will read one of the prayers.
