Tizer-to-Orangina group AG Barr said it expected its annual results to meet expectations despite challenging market conditions.

The Glasgow-based soft drinks maker said it had performed well in the face of strong competition as manufacturers fought for business during last year's poor summer.

In September, Barr said both Irn-Bru and Tizer increased their market share and helped lift half year sales marginally to £66.3 million amid "challenging" market conditions.

Chief executive Roger White said in a trading update ahead of its full year results on March 30 that increased marketing, strong sales work and continued cost controls had improved trading performance.

"Market conditions have been very competitive, but despite this, AG Barr has performed well," he said.

Barr employs nearly 1,000 people across the country at sites including Atherton, Kirkcaldy, Fife and Bristol. It has franchise deals in countries including Canada, Australia, Spain and Russia.
