Boris Johnson has outlined strict new measures to tackle the spread of coronavirus, including a ban on public gatherings of more than two people.
In a televised statement on Monday evening, the prime minister ordered people to leave their homes only under a list of “very limited purposes”.
He also ordered the immediate closure of shops selling non-essential goods.
But police chiefs warned of phone lines being inundated with calls about what movements were still permitted.
As of Monday, some 335 people have died with the virus in the UK.
