UK-based Elementis plc, whose products are used in leather tanning, timber treatment and metal finishing, has announced that the company's CEO, Geoff Gaywood, has resigned from his position, and will step down from the Board with immediate effect.

Edward Bramson, currently non-executive chairman of Elementis, will become executive chairman.

The company recently reported a half-year loss of £3.1m after heavy exceptional charges, but said revenues had improved in all four of its divisions in the first half.
