A Guard of Honour of hundreds of officers paid their respects as attendees at the Service walked from the Police Memorial on the Mall to the Royal Military Chapel in Westminster, also known as the Guards Chapel, to remember Sgt Ratana.
His partner Su Bushby, Home Secretary Priti Patel, Met Commissioner Cressida Dick and Mayor of London Sadiq Khan were the last to walk down the Guard of Honour.
Also stationed outside the chapel were a quintet of pups that make up the “Ratana Litter” with their officer handlers, as well as two officers from the mounted branch. Matt’s partner Su named the litter earlier this year.
Inside the chapel, Reverend Prebendary Jonathan Osborne, Met senior chaplain, led the hour-long service featuring hymns, readings and tributes, including from those representing Sgt Ratana’s different passions outside of policing – rugby and motor biking.
A Maori hymn was sung by Ngati Ranana, a New Zealand cultural group.
Dame Cressida said: “When Matt was sadly taken away from us Covid-19 meant we weren’t able to mark his death with a force funeral in the way that we would have wished to afterwards.
“We promised at the time that when restrictions weren’t in place we would arrange a special memorial service that would allow us all to come together in Matt’s memory, and I am delighted that today, we can finally honour that promise by gathering to pay him tribute.
“Matt has very much been in our thoughts over the last year, both as we grieved for him, but also as we planned for this very special day where we will remember and give thanks for his life.
“There will be sadness and reflection of course, but also celebration and much joy, for all the many lives he touched and the positivity and dedication with which he served.”
