Covid: PM agrees to publish data behind England's new tier system

Boris Johnson has agreed to publish the health, economic and social data behind England's new tier system later, as he seeks to avert a Commons rebellion. MPs will vote on the measures on Tuesday, and numerous Conservative MPs have demanded to see the data the government is basing its new system on. Writing to members of the Covid Research Group of MPs - who are sceptical of the new rules - Mr Johnson asked them to show 'unity and resolve'.
