Tobacco manufacturer Gallaher Group, which is set to be acquired by Japan Tobacco, has reported a 9.6% increase in full-year pre-tax profit to £565m on sales up 2.3% at £8.401bn.

Group cigarette volumes rose 5% to 182.4 billion sticks, the company added.

“These results again demonstrate our successful strategy,” said CEO Nigel Northridge. “I believe the offer from Japan Tobacco reflects Gallaher's achievements.”
