Exports, though, are increasing and account for 10 per cent of volume sales. Cash flow remained positive, and the company's bank balance at the end of June topped pounds 9m. Capital expenditure this year is being doubled to pounds 4m.
First-half earnings per share eased from 14.8p to 14.4p, but still left plenty of scope to increase the interim dividend from 5.1p to 5.4p. The share price closed unchanged at 543p.
