Britain's Prime Minister Boris Johnson stands outside 10 Downing Street to join in the nationwide Clap for Carers to recognise and support National Health Service (NHS) workers and carers fighting the coronavirus pandemic, in London, Thursday, May 21, 2020. The COVID-19 coronavirus pandemic has prompted a public display of appreciation for care workers. The applause takes place across Britain every Thursday at 8pm local time to show appreciation for healthcare workers, emergency services, armed services, delivery drivers, shop workers, teachers, waste collectors, manufacturers, postal workers, cleaners, vets, engineers and all those helping people with coronavirus and keeping the country functioning while most people stayed at home in the lockdown.
