I have been waiting to book my holiday abroad until everything eased, but I have just booked 3 return trips from Liverpool prior to Christmas. Its viable because now I don't need to self-isolate on return because:
A/ I'm not travelling to the USA or Brazil
B/ Other than the above, its safer abroad
C/ Apparently self isolation is not a 'law' to be broken, merely an 'instruction'.
D/ If its good enough for the Government, even if infected, its good enough for me when i'm not (touch wood)..
