The Scottish government’s decision to move Midlothian down to level two from Tuesday 24 November is “fantastic news for local communities and businesses”, according to its council leader.

Councillor Derek Milligan said: "The decision reflects the significant progress we’ve made in reducing the spread of the virus locally.

“With Christmas coming up, we all need to continue to do our bit to give everyone the best chance possible of celebrating with their families safely. That means keeping infection rates down."

Returning to tighter lockdown restrictions "makes Christmas an increasingly bleak prospect", according to the Scottish Chambers of Commerce.

Chief executive Liz Cameron said: "Businesses have done their utmost and have stuck with it through initial lockdowns and restrictions. They are now running on fumes.

"They have invested significantly to ensure they’re operating safely and can rightly feel aggrieved that commitments on test and trace which are supposed to be another key method of reducing the harm of both the virus and the lockdowns have so far fallen short."

Scotland’s largest teachers' union says schools in level four areas must be allowed to move to blended learning.

The EIS is highlighting rising numbers of teacher and student absences.

It wants schools to be able to move to blended or remote learning.

This would see pupils in schools part-time and working from home or online the rest of the time.

This would limit the number of pupils in school at any given time.

Some councils prepared plans for blended learning which would have seen each pupil in class two days a week or with different pupils in on different weeks.

The Scottish government has made it clear schools will stay open with no additional restrictions.

However, individual schools may still be closed because of specific concerns.

Scotland's largest teaching union has called for schools in level four areas to be allowed to implement blended or remote learning contingency measures.

EIS general secretary Larry Flanagan said: "In areas that are now at level four, the current policy of keeping schools operating as normal on a full-time basis is at odds with delivering effective virus suppression.

"It is not only about the safety of schools themselves, it’s about the role of schools in terms of local community transmission.

"It’s difficult to imagine somewhere with more social mixing than schools and pupils and staff then go back into their communities and their homes and families.”

People living in level three or level four local authorities will be breaking the law from Friday if they make non-essential journeys outside their own council area.

First Minister Nicola Sturgeon told MSPs Police Scotland will have the powers to enforce the new restrictions.

The legislation was announced as 11 of Scotland's 32 local authorities prepare to go into level four lockdown.

The Confederation of British Industry says the new restrictions are a "body blow".

Tracy Black, CBI Scotland director, said: "Businesses, particularly in the hardest-hit hospitality, retail and tourism sectors, have been told continuously that they must endure short-term pain for long-term gain.

"With many firms still operating under what were originally described as short, sharp restrictions, we now need a firm guarantee that the Scottish government will stick to their timetable for lifting level four restrictions."

She added that firms also wanted evidence that closing would reduce transmission of the virus.

Drivetime is about to start on Radio Scotland with all the reaction to the announcement that large parts of west and central Scotland are moving to level four restrictions.

Over two million people in 11 council areas will effectively go back into lockdown from Friday.

All non-essential shops and businesses will close, however schools will stay open.

It will also be against the law to travel outside level four areas - or into them.

Drivetime will try to explain what these restrictions mean and how they affect you. You can of course listen here with us on the live page.

The leader of North Ayrshire Council has expressed his relief that the area has not been put into the top level of restrictions - while neighbouring South and East Ayrshire have.

Cllr Joe Cullinane said the area's case rate had halved in recent weeks.

He said it should now aim to move from level three down to level two.

The Scottish Licensed Trade Association has described the move to level four in much of the west of Scotland as the “worst possible news for the licensed hospitality industry".

It said many operators will now be seriously considering if businesses have a future at all – "that’s how serious the situation is".

A statement from the trade body added: “Moving into level four suggests closing pubs and bars in October in five health board areas, has done little to bring down infection rate.

"Yet again, no meaningful engagement with our industry and no evidence (that the) virus is being spread within the licensed hospitality sector”.
