Bunting was hoisted on city streets, 1940s’ costumes were worn and songs sung to mark the occasion, with villagers in Helpston and Etton even able to see a restored amphibious vehicle (DUKW) from the war pass through the streets.
The parties began after a two minute silence was held at 11am, while wreaths were laid at All Saints church in Park Road.

Among the places to commemorate the occasion in style - despite the social distancing restrictions - were Everingham in Orton Brimbles, Spencer Avenue in Stanground and Newcastle Drive in Orton Longueville.
Peterborough Cathedral also held a virtual service at 3pm for people to watch from their homes.
The service was led by the Dean Christopher Dalliston and Canon Ian Black, the Vicar of Peterborough.
