The Government is being urged to delay Step 4 of the roadmap from June 21 due to rising Indian variant cases THE Government should be “cautious” about fully lifting lockdown measures in England due to the rise in cases of the Indian 'Delta' variant which could lead to hospitals being overwhelmed, experts have warned. Scientists are warning that hospitals could be overwhelmed by cases if the opening goes ahead - with all social distancing laws scrapped and normality finally resuming. The warning comes despite more than 40 million people having had their first jab - 78 per cent of the country - and 29m fully vaccinated - 55 per cent of the country - and hundreds of thousands of people getting vaccinated every day, with the opening up to over 25s of the vaccine seeing millions rush to get the jab.
