Nicola Sturgeon is due to outline how each area of Scotland will be impacted by the tiered lockdown restrictions.

The new graded system is to come into effect on Monday after the proposals were backed by the Scottish Parliament.

It will be a five-tier system, ranging from the baseline Level 0 to the highest Level 4.

The First Minister is expected to announce which local authorities will fall into each category, during First Minister’s Questions on Thursday.

Local leaders in Lanarkshire have pleaded with the Scottish Government not to impose the toughest coronavirus restrictions in the area – warning they could have “potentially catastrophic impacts” on local businesses.

North and South Lanarkshire are the only two authorities on which the First Minister has been considering imposing the toughest restrictions straight away.

If the area is placed in Level 4, bars and restaurants will remain closed while non-essential shops will also have to shut, along with hairdressers, gyms, libraries and visitor attractions.

Much of central Scotland, including Edinburgh and Glasgow, as well as Dundee, could be placed straight into Level 3 when the tiers are introduced from Monday.

In Level 3, bars and restaurants are not permitted to sell alcohol either indoors or outside, and must close by 6pm.

Ms Sturgeon indicated the Highlands Council area, as well as Orkney, Shetland, the Western Isles and Moray, could all go straight into Level 1 – the second lowest tier – in the new plan.

But while being in Level 1 could allow people to meet in other’s homes again – six people from two households are permitted to meet indoors in such areas – the First Minister said the restriction on indoor gatherings would remain in place “for a period as an extra precaution” as Scotland transitions to the new system.
