Police colleagues will pay their respect at today's funeral service, held in Sussex.

Metropolitan Police Commissioner Dame Cressida Dick will be among the speakers representing colleagues, friends and family paying tribute to the New Zealand-born Sgt Ratana.

It will be led by Prebendary Jonathan Osborne MBE, senior chaplain at the Metropolitan Police, and Maori speaker the Ven Jo Kelly-Moore, Archdeacon of Canterbury.

Previous tributes paid to Sgt Ratana following his death remembered the police officer of almost 30 years as a "gentle giant" and "irreplaceable figure" who was part of the "police family".
