Basically the most vulnerable that's 1500000 people will get letters to say they must stay in for 12 weeks - full details on govt web site - NHS to send out letters etc direct to them .Local councils and military to be more involved in logistics - we are basically shielding the most vulnerable - another impressive session from Boris and his experts IMO.He emphasized its essential people seriously keep to the rules of social distancing - I suppose if the selfish arrogant morons who don't comply then we will sooner than later all be forced to !!!
