Chair Daren Egan joined the Home Secretary and police chiefs, families, friends and former colleagues of the fallen at Waterfront Hall in Belfast on 25 September to pay tribute to officers’ commitment, courage and sacrifice.

Daren said: “It is a huge honour to be here representing Sussex officers, and actually all the officers in the UK, particularly in Northern Ireland. This force, probably more than others, have sacrificed the most. We’re here to remember the ultimate sacrifice they made.

“It puts it all into perspective, the job we do. It is very humbling to be here and represent Sussex.”

Members of the Royal family, who would normally attend, were absent as they are still in mourning for HM Queen Elizabeth II.

The names of officers who lost their lives over the past year were read out at the event by Liam Kelly, chair of the Police Federation of Northern Ireland. They are: PC Daniel Golding, of the Met; PC Craig Higgins, of Greater Manchester Police; PC Alex Prentice, of Northamptonshire Police, and PC Darryl Street, of the Civil Nuclear Constabulary.

Home Secretary Suella Braverman, who gave a reading during the service, said: “To all the officers who lost their lives while working to keep us safe, we thank you and we honour you.

“Their bravery and commitment to their duty was unfaltering – society owes them and their loved ones a debt we cannot repay, but it is one we will not forget.

“As Home Secretary I make a promise to give police the powers and tools they need to do their jobs safely.”

During the service, candles were lit by relatives in remembrance of officers throughout the country who have lost their lives – one from each of the four nations of the UK.

Representing Northern Ireland was Stephen Wylie-Young, son of Constable William Raymond Wylie QPM. Stephen was just six months old when his father was murdered.

Representing Wales was Sgt Lowri Davies, daughter of PC Terence John Davies, of Gwent Police.

Representing Scotland was George Barnsley, friend and colleague of DS William Ross Hunt, of Strathclyde Police.

And representing England was Kathryn Dumphreys, widow of PC Nick Dumphreys, of Cumbria Police.

There was silence as petals of remembrance, representing all who have lost their lives, descended from the gallery as the Last Post was sounded.
