Boris Johnson will order police to enforce a strict coronavirus lockdown, with a ban on gatherings of more than two people and strict limits on exercise, as he told the British public: "You must stay at home."

The prime minister ratcheted up Britain's response with an address to the nation on Monday evening, warning that people would only be allowed outside to buy food or medication, exercise alone once a day, or to travel to work if absolutely necessary.
