I totally agree we are spreading the virus by allowing it into our country through poor checks at our borders, but if people like the chap you mention going to South African do not seem to care then unless we shut our borders completely we will never stop it coming in ? There are many more people like him who will just do what they want, I have seen posts elsewhere from many of them.
To be brutal, stop all flights into the UK unless they are cargo or air ambulance, I do not give a damn about business people having to travel, the economy has a way of bouncing back, every life lost is gone forever, just think it could be a member of your family next all because of someone who found it essential to travelled abroad.
