The traditional Durham Miners' Gala, which typically attracts a crowd of 200,000 people, has been cancelled four months before it was due to take place due to the coronavirus crisis.
The Durham Miners' Association (DMA) said the decision to pull its annual event, known as the Big Meeting and which features pit banners and brass bands parading through the streets, was taken to relieve the burden on public services.
Labour leader Jeremy Corbyn has regularly spoken at the gala in recent years, and it is one of Europe's largest trade union events, bringing thousands to listen to speakers on the Old Racecourse, as well as families enjoying fairground rides.
The DMA said previously only world wars and two national strikes have prevented the gala from going ahead since the first was held in 1871.
Secretary Alan Mardghum said the gala would be back for 2021 - its 150th year.
