New face mask rules are set to come into force in England on Saturday amid a rise in the presence of coronavirus in the country.
People in England have had to wear a mask on public transport since the beginning of July, with the rule altered to include shops on July 24.
Indoor venues, including shopping centres, banks, railways, bus stations and airports were added to the rules too later.
On Saturday, restrictions will be imposed further, with fines of up to £100 given to those who refuse to abide by the rules.
From Saturday, August 8, people will have to wear a face mask in most indoor areas, including places of worship and museums and galleries.
Full list of places you will have to wear face covering from Saturday:
Anyone who fails to wear a face covering will be subject to a penalty, with a fine up to £100, reduce to £50, if paid within 14 days.
Enforcement of the rules will be carried out by police, and not retail staff, and the Prime Minister said there will be a "greater police presence."
He said the increased presence would be to ensure the public is adhering to requirements around face coverings.
The Department for Transport, however, said rules will be enforced by police and transport staff with fines of £100.
