Effective this evening which on the far side of the Atlantic is just about now, Brits are confined to quarters.
Prime Minister Boris Johnson announced the decision on Monday evening after a surge in coronavirus cases suggested that the UK is just two weeks behind the level of outbreak currently being seen in Italy.
"From this evening I must give the British people a very simple instruction - you must stay at home," Johnson said in a televised statement from his Downing Street residence.
The prime minister announced that from Monday evening the British people would only be allowed to leave home for the following "very limited purposes":
Shopping for basic necessities, as infrequently as possible
One form of exercise a day - for example a run, walk, or cycle - alone or with members of your household;
Any medical need, to provide care or to help a vulnerable person; and
travelling to and from work, but only where this is absolutely necessary and cannot be done from home.
