Irn Bru maker AG Barr has announced it will axe 90 jobs amid a drop in sales.

The Lanarkshire-based firm, which also makes Tizer and Snapple, said the move comes as part of its restructuring plans in a bid to save around £3m each year.

Revenue at the Cumbernauld soft drink maker plummeted from £130.3m to £125.6m in the first half of the year to the end of July. Profits, however, saw a slight increase from £16.9m to £17m.

The jobs will be shed from the firm's commercial, central office and supply chain departments.

A spokesperson said: "Our organisational restructure is likely to impact around 10% of our total employee base, and as such around 90 job losses are possible across our commercial, supply chain and central functions.

"Subject to consultation, we expect that the majority of the changes will be implemented before the end of the current financial year."

The spokesperson added: "In line with general market trends, lower and no sugar products have performed better as consumers respond to the significant weight of negative media coverage pointed towards added sugar products particularly in the last six months."

The announcement comes after the firm said earlier this year that it expects "at least two thirds of our portfolio will be lower or no sugar" by the time the levy is introduced in April 2018.

Around 40% of the group's portfolio currently has a low sugar content. The drinks sector was sent reeling by the announcement of the tax in the Budget earlier in March, which aims to raise around £520m a year to help fund sports for schools.
