Glasgow is the only part of Scotland still in level three, and some businesses have criticised the decision to keep it under stricter measures.
The new Scottish Health Secretary said ministers wanted to ease restrictions as soon as possible and hoped after this week it would become clear whether case numbers had led to a rise in ICU patients.Yousaf said the “critical question” is whether infections caused by the new Covid variant, so-called Indian variant, lead to more severe disease.
