Parts of Scotland have been warned that they could be moved into the strictest level of coronavirus restrictions.

No council area has been placed in Level 4 of Scotland's five-tier system, but alarm bells have been sounded in areas such as Glasgow and Lanarkshire that "active consideration" is being given to moving into the top level.

HeraldScotland:

Councils in the west of Scotland have been told it is a possibility.

But if areas were to move from Level 3 to Level 4, what would change?
