Är det inte "inom 2 dagar" som gäller?
Har några vänner som åkte till London för någon månad sedan. Dom tog testet direkt när dom landade på flygplatsen, så var det klart.
Ja, frasen är "on or before day 2".
Kanske lika bra att klisyra in hela
originaltexten från gov.uk, inklusive instruxerna om vad man ska göra om man testar positivt.
