Or will he also have to have a pre-departure test?
Also, can it be a lateral flow test, or does it have to be a PCR? There is a list of four tests that are approved, but I can't work out whether one of them is a LTF or not!
This is the list of approved tests from the British Airways website:
RT-PCR Test
TMA Test
Nucleic Acid Test
RT-LAMP Test
