Boris Johnson announced today that the final stage of the roadmap will not go ahead on June 21.
As of next Monday, all remaining coronavirus restrictions were due to be lifted, in what had been dubbed "freedom day."
But due to the rise of the Delta variant, and a risk of a 'surge' in hospilisations, the last stage of lockdown easing has been delayed until Monday, 19 July.
However, some restrictions which had still been in place, including on weddings and wakes, will be lifted as planned on June 21.
Other rules such as social distancing, mask wearing, and a ban on large events will have to remain in place for the foreseeable.
These are all the rules that will and won't be in place from June 21.
Social distancing and masks
General laws on masks in shops and on public transport remain in place, and are not being lifted from June 21.
Social distancing guidance was updated on May 17 to allow people more intimate contact with relatives and friends.
The government says that social distancing is now a choice for close family and friends - that means hugging and hand-holding will no longer be advised against for anyone but your own household.
The blanket removal of social distancing will not be removed on June 21 though.
Wider social distancing rules will remain in places in places like adult social care, medical, retail, hospitality and business settings until further notice.
Gatherings of up to 30 people are still allowed outside, but gatherings of more than 30 people will not be able to go ahead on June 21 (with some exceptions including weddings which you can read more on below).
Indoors, people are still only able to meet socially in a group of six, or with one other household.
Overnight stays at other people's homes are still allowed in groups of up to six people or two households.
Support groups or parent and child groups can still take place with 30 people - this limit does not include children under five.
The same rules to holidays abroad remain, despite today's announcement.
Travellers will still have to abide by the government's traffic-light system, which is updated regularly.
Much like with social gatherings, indoor hospitality will remain open but only to groups of six.
Restrictions on this number were due to be lifted on June 21, but will now not go ahead until at least July 19.
Up to 30 people can meet at hospitality venues outside.
There are no changes to indoor hospitality rules, or any changes to allow large events to go ahead in a blanket way without social distancing.
But the government is looking at holding more events research pilots which could help theatres and similar venues in the long run.
"We appreciate the pressure that some sectors are under", No10 said.
Universities, schools and work places
There are no plans to reintroduce masks in schools - though there is an element of local decision-making based on cases in their area, such is the case in Greater Manchester.
Local authorities retain the ability to change their approach in areas where there are sig outbreaks - but "we're confident our guidelines are the right approach”, said No10.
Although most universities have now finished for the summer, in-person teaching can still remain in place.
Advice to work from home where possible will continue to apply after June 21, due to the delay to step four.
Weddings and wakes
The 30-person limit on other commemorative events including wedding and wakes will be lifted in England from June 21.
That means there will be no numerical limit on either receptions or ceremonies - either indoors or outdoors.
Instead, capacity limits will be the highest number of people venues can accommodate while still being Covid-secure.
This is the approach that is already taken at funerals.
The 30-person limit will also be lifted on weddings outdoors on private land, including in gardens. There will be a risk assessment which organisers need to fill out.
But other restrictions on weddings - including the ban on most singing and dancing, and guests having to wear masks at certain points - will remain in place until step four.
People at an indoor venue will need to be on tables of no more than six people. Indoor venues must shut off their dance floors - apart from for the 'first dance.'
Marquees on private land need to have two sides open to qualify as 'outdoors'.
The rule of six indoors still applies to weddings in private homes - except for deathbed weddings, which can have up to 30 guests.
Rules on visits outside care homes will be relaxed in England from June 21, despite the delay in other areas.
The PM’s spokesman said: "The requirement for residents to isolate for 14 days after visits out of care homes will also be removed in most cases."
It is not yet confirmed which cases will still require a 14-day isolation.
However, officials indicated care home residents won’t need to isolate at all after visits outside their home, apart from possibly hospital visits.
It’s not yet known if this will allow residents to have overnight stays with relatives.
Fuller guidance is due to be published by the Department of Health and Social Care.
