Because we didn't really have any sort of lock down in the UK, the Tories just said the police would need to informally enforce a non-rule. The met responded that they were not going to enforce anything that wasn't an actual rule. There were words said and a couple of high profile incidents which shows how little any sort of lockdown happened. I know I drove around the country still and no one ever asked why, and all my neighbours had garden parties with social gathers still happening.
