More than 500 relatives of police officers killed in the line of duty along with representatives from forces across the UK will gather for a special service in Staffordshire.
The annual Care of Police Survivors Service of Remembrance is being held at the National Memorial Arboretum in Alrewas on Sunday (20).
The Roll of Honour of the eight police officers and one member of police staff who have died on duty over the last 12 months will be read out.
Those remembered this year will be Pc Michael Chapman of West Midlands Police who died of a suspected heart attack in April and Pc Shazahan Wadud of the Metropolitan Police, killed after his motorbike was hit by a car in September.
The service will also remember Met Pc Andrew Duncan, hit by a car in September, Pc Tony Collins, Pc Kirsty Nelis and Captain David Traill, killed in a helicopter crash in Glasgow in November, Det Con Adrian Grew of Kent Police, killed in a crash with a double decker bus in December, Pc Mark Murtagh of Police Scotland, who died after his motorbike was in a collision with a bus in May and Det Con Sharon Garrett of Cambridgeshire Constabulary, killed in a five-vehicle crash last month.
Readings will be given by family members of fallen officers before force representatives lay wreaths to remember the thousands of officers who have died in the line of duty over the years.
The service will be preceded by the arrival of a convoy of police motorcycles together with the UK Policy Unity Tour, a group of 100 cyclists riding from the Police Memorial in London to the National Memorial Arboretum.
The service starts at 11am.
On Saturday (19) morning a group of children of fallen officers will be jumping out of a plane to raise money for the Care of Police Survivors (COPS) charity.
Organiser Vicki Moore, the daughter of fallen officer Pc Moore from Leicestershire who died in 2002, said: “Each of us is immensely proud of the everyday sacrifice our fathers made to protect our streets.”
The arboretum covers 150-acres and features more than 200 dedicated memorials. Around 50,000 trees have been planted at the site, with more being added each year.
