Boris Johnson has announced stricter face covering rules, amid worries of a coronavirus spike.
This comes as a further easing of lockdown across England has been postponed as the Prime Minister warned the country "cannot be complacent".
Face coverings will now be a requirement in indoor settings where you come into 'contact' with people outside of your usual party.
Speaking at a Downing Street press conference on Friday, Mr Johnson said: "We will also extend the requirement to wear a face covering to other indoor settings where you are likely to come into contact with people you do not normally meet, such as museums, galleries, cinemas and places of worship.
"We now recommend face coverings are worn in these settings, and this will become enforceable in law from August 8.
"At this stage, we are not changing the rules on social contact nationally. I don't want to tell people to spend less time with their friends. But unless people follow the rules and behave safely, we may need to go further."
Last night, local lockdown measures were announced in parts of the north west of England of parts of West Yorkshire, banning people from different households meeting indoors or in gardens following a spike in virus cases.
Mr Johnson added: "Two weeks ago, I said we would hope for the best but plan for the worst.

"And of course we continue to hope for the best. The way to get there and to achieve that optimum outcome is if we all follow the rules, wash our hands, cover our faces, keep our distance - and get a test if we have symptoms, so that NHS Test and Trace can keep the virus under control.
