The number of coronavirus clusters in Cornwall has risen from eight to 43 in the space of the week.

More than half the Duchy have now reported three or more weekly cases – and eight are into double figures.

The three areas showing the highest spikes are St Ives, Falmouth and Newquay, which have all seen cases rise by more than 2,000%.

However, Cornwall's lead councillor for health has this week denied that the spike is related to last week's G7 Summit, despite these areas being the three host sites.
