Face coverings will become mandatory in shops in Scotland from July 10, Nicola Sturgeon announced today.
The First Minister went a step further than England and unveiled a ban on entering retail outlets without a covering.
She later said police would be able to enforce the ban with fixed penalty notices, according to the BBC.
It goes a step further than the UK government, which has repeatedly stopped short of making face coverings in shops compulsory for England.
On May 11 the government announced guidance saying face coverings “may be beneficial in places where it is hard to follow maintain social distancing”, such as some shops.
But since then England has stopped short of making them mandatory despite them becoming so on public transport and for visitors in hospital.
Ms Sturgeon said the Scottish Government has been considering the issue of face coverings “for some time now”.
She said: “I can confirm today that from the expected start of phase three, which is July 10 next week, wearing face coverings will also be mandatory in shops.”
Children under five will be exempt from this rule, she added, along with those with certain medical conditions.
But she said: “For everyone else, face coverings will be mandatory.
“This is not a decision we have taken lightly, it has taken us some time to reach this decision.
“But as we all start to interact more, it is vital we take all reasonable steps to reduce risk and we know that face coverings can help reduce the risk of transmission indoors.”
During the Scottish Government’s daily coronavirus briefing, Ms Sturgeon also announced that the two-metre social distancing rule can be reduced in the hospitality and retail sectors and on public transport from July 10.
Pubs, restaurants and shops will be allowed to adhere to a one-metre rule instead, with mitigation measures in place.
But the general rule in law will be that businesses must take reasonable measures to ensure two-metre distancing is maintained, she said.
The First Minister also said 2,487 patients have now died in Scotland after testing positive for coronavirus, up by one from 2,486 on Wednesday.
A total of 18,264 people have tested positive for the virus, up by five from 18,259 the previous day.
Announcing the new measures, Ms Sturgeon said the science on physical distancing has not changed and there is an increased risk of somewhere between two and 10-fold in reducing the measure to one metre.
But she said that as the number of infected individuals falls, there is less chance of coming into contact with someone who has the virus so absolute risk is lower.
She added the Government recognises the two-metre rule has benefits, but it also has “serious economic implications” which can impact on people’s health.
“For those reasons when we enter stage three of the route map, which I hope will be the end of next week, we will allow exemptions for specific sectors where agreed mitigations must be put in place,” she said.
These mitigations could include improved ventilation, perspex screens and a requirement for businesses to collect the names and addresses of customers “to help with contact tracing when that is necessary”.
Ms Sturgeon also said that where a business operates at less than two metres, there must be clear signs informing customers “that they are entering a one-metre zone”.
Masks became mandatory north of the border on all public transport on June 22.
From July 15, Scotland is set to reopen indoor pubs, restaurants and hairdressers.
The First Minister also confirmed outdoor hospitality – such as pavement cafes and beer gardens – can open from Monday.
Self-contained holiday accommodation, such as cottages and lodges, can reopen from Friday.
The Scottish Government is also lifting the guidance advising people not to travel more than five miles for leisure from Friday – although this will not apply to parts of Dumfries and Galloway where there is a cluster of Covid-19 cases.
Ms Sturgeon said the changes are possible because the R number – the average number of people infected by each person with coronavirus – stands between 0.6 and 0.8.
She also said the number of people who are believed to be infectious with Covid-19 in Scotland had reduced to 1,500 by last Friday.
