Data suggests levels of covid are going down in all four nations of the United Kingdom. But how can we exit lockdown safely?

The data is more evidence lockdown is controlling the virus, even with the more infectious variants circulating - although the health secretary said there is "still a long way to go".

The latest R number, estimated to be between 0.7 and 0.9, also suggests infection numbers are shrinking.

This is the first time since July that R has been this low.

It means, on average, every 10 people infected pass it on to between seven and nine other people.

What is the plan now and what could the government’s strategy for unlocking look like?
