Fifty firms in Scotland have been revealed on a UK government list naming and shaming employers that failed to pay staff minimum wage.

Three of the companies topping the list in Scotland - including North East bakers Murdoch Allan & Son - each owed more than £20,000 to underpaid workers.

The Department for Business said 658 employers across the UK have been ordered to repay £4m after more than 27,000 workers have been left out of pocket.

Nearly 700 workers were affected in Scotland.

The largest amount underpaid in Scotland was by family-owned nursery chain Collin Care Ltd in Glasgow, which owed £28,149 to 77 workers.

Next came bakers Murdoch Allan & Son in Peterhead, which failed to pay £24,150 to seven employees.

This was followed by Fiona Burgoyne trading as Horsechoice - a horse dealer and showjumping yard in Edinburgh - which underpaid four workers by £22,422.

Several other nurseries based in Glasgow featured on the list, including Victoria Park Kindergarten, Clarence Nursery and Acorn Park Nursery.

Dynamic Retail Ltd trading as Scotfresh in Dundee failed to pay £14,452 to 215 workers, while Aulds Delicious Desserts in Renfrew owed £9,435 to 89 staff.

Also on the list were Glasgow restaurants La Vita and The Butchershop Bar & Grill, which underpaid 66 workers by £5,440.

Two companies - Saash Foods Limited and KA Scotland Ltd - trading as fast food chain Pepe's, failed to pay £2,587 to two workers and £700 to 14 employees, respectively.

Businesses in hospitality, retail, construction and food production were all represented on the list.

Around 2.7 million people in the UK received a pay rise in April as the national living wage went up by 50p to £12.71 for over 21s.

Workers aged 18-20 saw an 85p increase in national minimum wage to £10.85 and under 18s and apprentices got 45p more to £8 an hour.

For someone working full time, national living wage amounts to £24,784.50 a year.

Some workers do not qualify for either the national minimum wage or national living wage.

This includes people who are self-employed, company directors, volunteers, members of the armed forces and prisoners.

It is a criminal offence for employers not to pay the correct national minimum and living wages to eligible employees.

The rates apply even if workers are not paid by the hour.

Business Secretary Jonathan Reynolds said: "The best businesses know that looking after your workers isn't just the right thing to do, it's the smart thing to do.

"Most employers already understand this, and I want to work with them to ensure they have every piece of guidance and support available to help them follow the rules.

"Short-changing your staff isn't a shortcut to success and we are determined to stamp it out."
