30Three,
The sad reality is, that both Governments are now making all aspects of travel and business as difficult as they can, like a game of one upmanship. The cancelled Submarine contract from Australiajust compounded difficult times since BREXIT. We get the blame regardless, even though others awarded a British company a contract for a Nuclear Submarine compared to a Diesel/Electric one!! Nothing to do with countries but technology I'm afraid.
Hope your mum is well and welcome to England.
