The prime minister has announced a reduction in the two-metre social distancing rule, as he gave the green light for pubs, restaurants, hotels, hairdressers and barbers in England to reopen from 4 July.
Setting out the latest easing of the coronavirus lockdown, Boris Johnson said "our long, national hibernation is coming to an end" and "life is returning to our streets".
The PM said people will from next month be required to keep "one-metre plus" apart from others, while also taking measures to mitigate the risk of transmitting COVID-19.
"Where it is possible to keep two metres apart, people should," Mr Johnson said.
"But where it is not, we will advise people to keep a social distance of one-metre plus, meaning they should remain one metre apart while taking mitigating measures to reduce the risk of transmission."
Rules around 'shielding' to be relaxed
These include wearing a face mask on public transport, handwashing, screens, being outside and limiting time spent with others.
Another change to the guidelines from 4 July will allow gatherings of two different households indoors, provided social distancing is maintained.
This will mean families can be reunited and dinner parties will be allowed, but people will still be unable to hug their loved ones.
But the public have been warned life will not return to normal for a long time.
"I would be surprised and delighted if we weren't in this current situation through the winter and into next spring," England's chief medical officer Prof Chris Whitty warned at the final daily Downing Street briefing.
"I expect there to be a significant amount of coronavirus circulating at least into that time and I think it is going to be quite optimistic that for science to come fully to the rescue over that kind of timeframe."
Changes that will take effect from 4 July include:
Theatres and concert halls can operate once again, but cannot stage live performances
In a boost for domestic tourism, most leisure facilities and tourist attractions can reopen, while people will be allowed to stay overnight in hotels, bed and breakfasts and campsites
Wedding services of up to 30 people will be allowed, provided social distancing is maintained, with places of worship permitted to reopen
Outdoor gyms and playgrounds can be used once more
Community centres and bingo halls will be permitted to reopen
Although a raft of businesses will reopen in the weeks to come, Mr Johnson said nightclubs, indoor gyms and beauty salons must remain closed "for now".
Spas, casinos, nail bars, tattoo parlours, massage parlours, soft play areas, swimming pools, bowling alleys and water parks will also not reopen at this next stage.
Culture Secretary Oliver Dowden said it was the government's "aspiration" to reopen gyms and leisure facilities in "mid-July".
As with non-essential shops, which began operating again earlier this month, premises that reopen will have to introduce a range of safety measures to ensure they are "COVID secure".
Sector-by-sector guidance is due to be published for businesses, advising them what action they need to take to reopen safely.
'Coronavirus is still accelerating globally'
Pubs and restaurants will have to take the names and contact details of customers, in case they have to be contacted as part of the government's test and trace programme to contain the spread of the virus.
The announcement comes three months to the day since Mr Johnson took England into lockdown.
A total of 42,647 people have so far died in the UK after testing positive for the virus, according to government figures.
After telling people to remain indoors - with a few exceptions - for more than six weeks, the PM set out a roadmap out of lockdown in May.
Since then, the restrictions have been eased as more parts of the economy have been given the go-head to restart.
The PM said the progress made in the fight against the coronavirus meant steps could be taken to "safely ease the lockdown".
But he added that "caution will remain our watchword" with every step of relaxing the lockdown "scrupulously weighed".
Mr Johnson said the government's approach was to "trust the British public to use their common sense in the full knowledge of the risks, remembering that the more we open up, the more vigilant we will need to be".
Although there was an optimistic tone to Mr Johnson's message, he said the virus has not gone away and the government "will not hesitate to apply the brakes and re-introduce restrictions - even at national level - if required".
Labour leader Sir Keir Starmer said: "There are obviously a number of questions that need to be answered, but overall I welcome this statement.
"I believe the government is trying to do the right thing and in that, we will support them."
Prof Whitty cautioned that "the biggest thing I worry about" is people not self-isolating if they are told to by the trace and test team, who will try to track down anyone who may have been infected by someone with coronavirus.
Sir Patrick Vallance, the UK government's chief scientific adviser, added the news parts of society can reopen were "reasonable" - but risks are attached.
"It is not risk free. It cannot be risk free. Every time you take a step to open up there is some associated risk with that," he told the Number 10 news conference.
"You need to be prepared where there is local outbreaks to deal with them locally and if they become beyond local then you need to deal with them at regional and national levels which would mean reversal of some of the measures.
"That is the only way you can keep on top of this."
