Boris Johnson lockdown update: all the 1st August changes being postponed in England - and new face mask rules
The news comes after local lockdowns were imposed in parts of West Yorkshire, Greater Manchester and East Lancashire following a spike in virus cases.
Here are all the restrictions that won’t be lifted across England on 1 August as planned - and the new rules for areas under local lockdowns.
Which restrictions won’t be lifted on 1 August?
Some measures that were due to be lifted on Saturday (1 August) will be postponed for a further two weeks at least.
Face masks, which are currently compulsory in shops and on public transport, will also become mandatory in museums, galleries, cinemas and places of worship among other indoor settings.
These changes will come into force from 8 August, according to the PM.
England's Chief Medical Officer Chris Whitty also warned that it might not be possible to ease lockdown further.
Speaking at a Downing Street press conference on Friday alongside Prof Whitty, Boris Johnson said: "As we see these rises around the world, we can't fool ourselves that we are exempt. We must be willing to react to the first signs of trouble."
He said that with numbers rising "our assessment is that we should squeeze that brake pedal... in order to keep the virus under control".
Which areas have local lockdowns - and what are the rules?
It was announced on Thursday 30 July that in Greater Manchester, parts of East Lancashire and West Yorkshire, people from different households will no longer be allowed to meet inside their homes or in gardens.
The rules came into effect at midnight on 30 July and will be reviewed each week.
While people are still allowed to go to pubs and restaurants and other hospitality venues, they are not allowed to mix with anyone from outside their household in these places.
Hospitality businesses will remain open for those visiting individually or from the same household.
Are cases of coronavirus increasing in England?
There has been an increase in the number of people testing positive for Covid-19 in England according to The Office for National Statistics.
Between July 20 and 26 there were around 0.78 new Covid-19 infections for every 10,000 people in the community population in England, according to the ONS.
This is equivalent to around 4,200 new cases per day - up from an estimated 2,800 new cases a day in the previous week.
Prof Whitty told the briefing: "I think what we're seeing from the data from ONS and other data is that we have probably reached near the limit or the limits of what we can do in terms of opening up society.
"So what that means potentially is that if we wish to do more things in the future, we may have to do less of some other things.
"And these will be difficult trade-offs, some of which will be decisions for government and some of which are for all of us as citizens to do.
"But we have to be realistic about this. The idea that we can open up everything and keep the virus under control is clearly wrong."
