There has started to be lots of talk about social distancing in the UK being reduced to 1m rather than 2m.
I think the Gov will do this and hence allow a broad release of lockdown and re-start of the econonmy with schools and transport being best endeavours for 1m social distancing.
Remember the WHO use 1m (www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public)
