Boris Johnson has confirmed that the UK Government will not lift all restrictions in England from June 21.
He had repeatedly said that June 21 would be the day all restrictions in England were lifted, but the spread of the Delta variant has mean that will now be delayed for a month.
There will be a review in two weeks but it is considered unlikely any restrictions will be lifted early.
If restrictions could be eased, it would be on July 5.
But in a blunder set to spark confusion - the Prime Minister wrongly said during televised Covid-19 briefing that the unlocking would be delayed until "July 29." The final step of the prime minister’s roadmap - which was to remove most remaining restrictions in England - is actually expected to take place from July 19.
Some changes are being made to weddings, care home quarantine and the vaccination schedule. Over the next four weeks, pilots of large events will continue with between 10 and 15 events taking place, some seated and some unseated operating up to full capacity.
The cap of 30 guests at weddings and wedding receptions in England will be lifted and instead capacity will be limited by a guests being able to socially distance within a venue.
At receptions, table service will be required, and people will still need to follow social distancing rules and when walking around a venue, masks will need to be warn.
Existing rules banning singing and dancing remain in place.
If people wanted to dance outside on private land, guidance will tell people they should not dance but it is guidance not a legal requirement. The law only applies to indoor at a venue.
If people are holding weddings in a garden or on private property and have more than 30 people they will need to complete a risk assessment.
A marquee is classed as an outdoor venue if it has two sides, if it has more than that the rules for indoor events apply.
Today's UK Government announcement also applies to wakes, but not to christenings.
In Wales, Welsh Government had already lifted restrictions and said that subject to meeting social distancing rules, events outside can have up to 4,000 people if seated.
People visiting care homes
The requirement for residents to isolate for 14 days after a visit out of a care home will be lifted "in most cases". Currently, if someone leaves a care home for a visit, they have to self-isolate for 14 days on their way back into the care home but that won't be required under the new rules.
There is an exception to that rule change if someone is returning from hospital.
The UK Government say it hopes the four week delay will mean that by the end of the period, two thirds of adults will have been vaccinated.
The time between vaccinations for over 40s will be reduced from 12 to eight weeks and all over 40s who were offered their first dose by mid-May will have been offered second by the week beginning July 19.
Also by July 19, all those in groups one to nine will have been offered their second vaccination dose and all over 18s will have had their first dose.
It will mean around two thirds of adults will have been offered both doses by that point.
Transmission is currently taking place between younger age groups, the data shows.
People will be contacted by the NHS when they are eligible for their jab.
In Wales, all adults have now been offered a first coronavirus vaccine - six weeks ahead of schedule.
Vaccination clinics across Wales are now accelerating second doses amid growing concerns about the spread of the Delta variant of the virus across the UK. In Wales, it is hoped that 18 to 39-year-olds will have been vaccinated with a 75% take-up rate by the end of June.

What isn't changing?
No changes are being made to furlough - which also applies in Wales. Until July, that remains on offer to businesses, but the amounts will be phased down until it is stopped in September.
From July 1, the Government’s share will fall to 70% with employers contributing 10%, as part of a staged withdrawal of the scheme due to finish completely at the end of September.
The UK Government say that measures were put in place until autumn knowing there could be delays over the summer.
People should still work from home where possible, according to the UK Government.
A promised review on social distancing will be published when the UK Government moves England to step four.
