He has battled against bypasses, for his rights, a sword and to access Stonehenge, and now the once and future king of this sceptred isle is seriously venturing into politics for the first time.
King Arthur Uther Pendragon, the druid campaigner and perennial thorn in the side of English Heritage, Wiltshire police, Salisbury council and the nation's road-builders, has launched his own political party – and immediately given it to the rest of us.
King Arthur's new party is to be called The People's Party, and is based on the premise that 'we have no manifesto'. "It's a party by, for and of the people – real democracy," he said.
The veteran eco-warrior and pagan campaigner has stood for election before, but always on his own and in one particular seat. Several times he has polled more votes than one of the mainstream parties, and now in the run-up to the May 2015 general election he is, sort of, forming a party to be a collection of independents, each fighting for the area they want to represent.
"Independent candidates will if, as and when elected, represent the people rather than the policies, making it their business to find out what the people of their constituency want, and to argue for it in parliament," said King Arthur.
The former soldier and biker, known in a previous existence as John Rothwell, realised he was a reincarnation of King Arthur during the mid-1980s. He became a leading figure of the anti-bypass campaign in Newbury and of other road protests of the 1990s, before leading the fight to reopen Stonehenge at summer solstice, which had been closed since the Battle of the Beanfield in 1985.
Having won that victory, in 2000, he is still protesting outside Stonehhenge, this time in protest at the decision to display human bones in the new visitors' centre.
Now, he believes The People's Party could change the face of democracy. "The people are tired of the same old political rhetoric and are completely uninspired by the present political system where nobody listens to their views," he said. "It's about time we did something about it and took back control. That's the point of the PP: free independent politics, by, for and of the people.
"If the people of Portsmouth and Liverpool want more investment in the docks then that is what their PP member or representative will fight for, and if the people of Nottingham and Birmingham are against it, then that is what their PP member or candidate will speak out against."
He is now encouraging people of whatever political persuasion to stand as independents at the next General Election under the banner of the PP, with King Arthur himself standing as the proposed parliamentary candidate for Salisbury, against sitting Tory MP John Glen.
The party slogan is 'If you don't like what's on offer, get out there and do it yourself'. Last time King Arthur stood for election, in Salisbury in 2010, he polled 257 votes, and finished second from last.
"You can have a Scottish MP representing a Welsh constituency and living in London, but in reality representing no one, save their party line and, let's face it, there's not much between them," he added.
