England's lockdown to ease as planned on 12 April
Pubs and restaurants serving outside can reopen seeing as planned next Monday, along with non-essential retailers, gyms and hairdressers, while England's lockdown is further eased, the PM has said.
But Boris Johnson urged caution, saying: "We can't be complacent."
Officials were examining the potential role of Covid status certificates, he told a Downing Street briefing.
Pilot events will need place from mid-April to trial the system, with later events checking vaccinations.
Speaking in Downing Street, the prime minister also said the government was "hopeful" international travelling could resume in the next stage of lockdown easing upon 17 May, but cautioned against the consequences of the surge of coronavirus in other areas of the world.
He said the federal government would lay out "prior to 17 May what's reasonable" and try to supply the aviation industry "seeing that much notice as possible".
It comes simply because the federal government has published an update over some reviews into Covid certificates, the safe return of mass events, international travelling and social distancing rules.
In the document, the federal government says it cannot yet confirm international travel can resume on 17 May "given the state of the pandemic abroad", and advises people not to book summer holidays abroad "before picture is clearer".
In addition, it confirms further details on a good risk-based "traffic light" system for foreign travel can be published found in a written report later this week.
On Covid status certification, the paper says this may have a significant role to play both domestically and internationally and "will probably turn into a feature of our lives" as the pandemic continues.
A documentation scheme could record whether people have been vaccinated, recently tested negative or had natural immunity.
The NHS is working on digital and non-digital ways for folks to show their Covid status, based on the government paper, but there were no information on whether this might include using an app.
A lot more than 40 Conservative MPs have signed a cross-party letter opposing the utilization of vaccine passports for access to jobs or services, with critics calling such a maneuver "discriminatory".
