lockdown restrictions are required to bring down the number of people catching Covid-19.Transmission of the virus is on the rise, with hundreds of new cases now being reported each day.One possible option being weighed up by ministers is a so-called "circuit breaker" lockdown.This could see non-essential shops and hospitality businesses told to close temporarily and travel restrictions on the public reimposed.While no final decision has been taken, such a course of action has been hinted at by politicians and health experts in recent days.The First Minister last week hinted a two week "circuit breaker" lockdown may be needed if people don't stick to existing lockdown measures.The SNP leader was asked about the possibility after John Swinney.
