Get back to work if you can't do the job at home, but don't use public transport, the PM told the country this evening on television. He went on to unveil a "conditional plan" to reopen society, allowing people in England to spend more time outdoors from Wednesday. He introduced a new COVID Alert System with five levels that would govern how quickly lock-down restrictions could be eased. He hoped the next step "at the earliest by 1 June" would be for some primary pupils to return to school in England. The return would be phased, with Reception, Year 1 and Year 6 returning first if infection rates and the government's other tests at the time allowed it. There's a new slogan now, which reads: "Stay alert, control the virus and save lives." I am not sure what the 'alert' bit stands for, but there we go. In Scotland, Nicola Sturgeon stuck to the "stay at home" message, putting her at odds with England.
