Boris Johnson misspoke several times at tonight's press conference, referring to Britain as a 'company' and giving the wrong date for the new Freedom Day. The Prime Minister dramatically delayed the country's unlocking by another four weeks after scientists warned the Indian variant could be 80 per cent more infectious.But he made a handful of errors during tonight's announcement, saying there would be a delay in the lifting of restrictions to July 29 - which he later corrected to July 19.  The PM also said 'once the adults of this company', when he meant 'this country'.Britons poked fun at Mr Johnson, joking that he was 'probably hungover' following an eventful G7 Summit in Cornwall at the weekend. One Twitter user said: 'Boris Johnson has now said to add to July 29th (wrong date, he meant July 19th) that he hoped the company (he meant country) will be vaccinated. This is going terribly well.' Others said he was 'recovering from his weekend booze-up', or was simple 'a bit knackered'.   The Prime Minister dramatically delayed the country's unlocking by another four weeks after scientists warned the Indian variant could be 80 per cent more infectiousBritons poked fun at Mr Johnson, joking that he was 'probably hungover' following an eventful G7 Summit in Cornwall at the weekendMr Johnson defied fury from Tory MPs and the hospitality industry to insist he could not press ahead until more people have had two vaccinations, saying the disease cannot be 'eliminated' and the country will have to learn to 'live with it'.'I think it is sensible to wait a little longer,' he said. 'Now is the time to ease off the accelerator.' However, Mr Johnson added that he viewed the new date as a 'terminal point' for lockdown, with all restrictions able to be lifted for good.  The shift came after Government experts told the premier that the Indian - or Delta strain - is far more transmissible than the Kent version, while single doses of vaccines are thought to be less effective in countering it.Allowing the relaxation in England could put millions of people who have yet to have a jab at risk, as well as those who have only had one dose and elderly people who remain vulnerable.Chief medic Chris Whitty, flanking the PM as usual alongside Sir Patrick Vallance, told the briefing: 'The assessment of risk has fundamentally shifted.' The move means that current rules will essentially remain in place until July 19 - with social distancing in force in bars and restaurants, and the edict to work from home where possible staying.Giving the bad news at a Downing Street briefing, the PM defied fury from Tory MPs and the hospitality industry to insisted he cannot press ahead until more people are double-jabbedAt the same time the vaccine rollout will be intensified, with dosing intervals reduced to eight weeks. As a result around two thirds of adults could have been double-jabbed by July 19. Government experts say hospitalisations should be slashed by between half and a third as a result, preventing 'thousands' of deaths. Modellers have indicated that otherwise hospital admissions could hit 2,000, with 250 or even 500 deaths a day possible.  In an effort to sweeten the pill for people who have been putting their lives on hold for more than a year, there will be some easing on the rules for weddings. The 30-person limit on services and receptions will be abandoned - but venues will still be restricted by how many they can accommodate while respecting social distancing rules.Dancing will also still be out in another blow to couples hoping to celebrate.
