Many people travelled to this from (relatively) far, Cornwall, Devon etc. and had never been on a protest before. That part of the country does have a very western-medicine sceptic reputation. A bit hippy new-age. It was also a distinctly white middle-class demographic, although not exclusively. A friend of mine was in the same area a few hours later and she said it was back to normal. Busy shops, most people in masks again. Definitely a significant protest for the UK though.
