The 'R' rate in every nation in the UK appears to now be below 1, according to a survey, as deaths surge in the coronavirus second wave.
The latest King's College analysis suggests the transmission rate of the virus has dropped across all four nations - but risen in England's Midlands.
One source of data has uncovered the declining 'R' rate, putting it at 0.9 across England, Scotland, Wales and Northern Ireland this week.
But it comes before the impact of the latest lockdown restrictions have had time to be fully measured. The data comes from the ZOE Covid-19 Symptom app.
