This important annual event, hosted by the Police Federation of England and Wales, is a day to remember police officers who have been killed or died in the line of duty.
Mae’r digwyddiad blynyddol pwysig hwn, a gynhelir gan Ffederasiwn Heddlu Cymru a Lloegr, yn fodd i gofio am swyddogion heddlu sydd wedi’u lladd neu wedi marw wrth eu gwaith.
