The guidance for travel exeptions from the United Kingdom can be found at www.gov.uk/guidance/coronavirus-covid-19-declaration-form-for-international-travel#permitted-reasons-for-international-travel. The guidance notes that travel for funerals falls under a reasonable excuse, but commemorative events do not. All policies that were related to staying at home were applied equally and without prejudice - regardless of the event, religious belief or any other factor. For some time, the government has focused on ensuring the public know how to travel safely, however they decide to travel. This is important because people feel more confident travelling when they see other people complying with the same rules, for example wearing a face covering unless they are exempt.
