There must have been a lot of so-called Covidiots to be able to take those photos
I think they were taken by a reporter for Cornwall Live. As we know, media reporters are exempt from all lockdown rules, they can travel around regardless. I remember on the local BBC news during the 1st lockdown a reporter had dashed across Cornwall from Plymouth to challenge a surfer who had come a couple of miles to his nearest beach, which he explained. I'm waiting for someone to challenge a reporter & report him to the police.
So if you want to travel the country during lockdown, become a reporter, or Scotland's Chief Medical Officer, or Boris's adviser, or a celebrity chef (well Gordon Ramsey to be precise) or . .
