(220108) -- LONDON, Jan. 8, 2022 (Xinhua) -- A picture taken with a fish-eye lens shows passengers walking in Terminal 5 at Heathrow Airport in London, Britain, Jan. 7, 2022. Earlier Wednesday, British Prime Minister Boris Johnson led a cabinet meeting where he recommended sticking with England's Plan B, which includes work-from-home guidance and mandatory face masks in most public indoor venues. It's also been announced that pre-departure testing is no longer required for travellers returning to Britain. According to the new measures, arrivals do not have to isolate until they get a negative PCR test, but instead have to take a lateral flow test at the end of day two after arriving.
