Johnny Kingdom was among guests invited to a tea party to celebrate the first birthday of the Exmoor flag.
The flag was designed by Jenny Stevens from London. Her design was selected from a shortlist of five in a public vote.
It has gone global since its launch in October 2014 and has been spotted and mentioned all over the world, including in America; Canada; Italy; Spain; France; Germany; New Zealand; Zimbabwe and the Arctic.
It was flown at the Cricket World Cup in Australia, and was presented to the mayor of Pitcairn Island in the South Pacific – one of the remotest places on the planet.
The flag was used as a question by Jeremy Vine in the academic quiz show Eggheads flown at the Royal Albert Hall at the BBC Last Night of the Proms.
Philip Tibbetts, at the Flag Institute, said: “The Exmoor flag is such a special flag and the way it has been used so enthusiastically and with such versatility has made it a success within Exmoor.”
It is an official flag registered with The Flag Institute and is free to use by anyone who wishes to express their pride in the region.
