We have booked a last minute holiday to Spain so I am now getting my head round the tests rules. I dont need to isolate on arrival to the UK, i just do a test on day 2. What's the point of that? I could be walking around infecting anyone with my foreign germs on the day after I return. Surely I should be testing on arrival to the UK?! And with a family what's to stop me just buying one lateral flow, and then using the same code on our locator forms for each member of the family?
