Irn Bru makers AG Barr says that it will cut 90 jobs after announcing a fall in revenues.

The Cumbernauld-based drink firm, which also produces Rubicon, Strathmore Water and Funkin cocktail mixers, said the job losses were part of a drive to improve its 'services, efficiency and speed to market'.

A spokesperson said: "Our organisational restructure is likely to impact around 10 per cent 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."

It has been reported that the shake-up will create annual savings of £3m for the firm.

The announcement came as AG Barr confirmed it has suffered a drop in sales during the last six months, with revenues falling 3.6 per cent.

The company's overall revenue fell from £130.3m to £125.6m during the six months to the end of July. Like-for-like revenues dropped 2.8 per cent.

However, its profits increased to £17m from £16.9m during the same period in 2015.

A spokesperson told the Financial Times: "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."

It is estimated that higher import costs following the Brexit vote will cost the firm £3-£4m.
