British American Tobacco (BATS.L)said it sees 2021 as a "pivotal year" as it backed its full-year profit and sales forecasts on Tuesday buoyed by strong demand for its "new categories" products.

Its shares, down 3% this year, rose 1.75% to 2,671 pence in morning trading after the FTSE-listed company also flagged a possible share buyback.

The company said an additional 3.6 million customers used its "new categories" products - e-cigarette, tobacco heating and oral nicotine - in the year to end-September, bringing its total non-combustible user base to 17.1 million.
