British American Tobacco has reported an 18% increase in first-quarter operating profit to £807m on revenue up 14% at £2.541bn.

Revenue for the three months to 31 March was driven by favourable exchange, improved pricing and a better product mix, said British American Tobacco, which makes Lucky Strike, Kent, Dunhill and Pall Mall cigarettes.

“The year has clearly got off to a great start, with profit growth in all our regions,” said chairman Jan du Plessis. “While the normal caveats about not reading too much into any particular quarter still apply, the group's spread of business between developed and developing markets continue to serve shareholders well.”
