Covid circuit breakers 'doomed to fail', says disease expert

Covid circuit breakers are "doomed to fail", according to a disease expert.

It comes as Health Minister Vaughan Gething said a circuit lockdown was being "actively considered" for Wales.

The short-term measures could include closing pubs and restaurants.

But Dr Roland Salmon, former director of communicable diseases at Public Health Wales, said: "I simply don't think a circuit breaker will work."
