Tobacco firm Imperial Brands has reported flat full-year sales at £30.5bn and profits at £1.8bn as cigarette volumes dip and vaping grows.
Imperial's chief executive Alison Cooper tells the Today programme: "At Imperial, we are looking to offer something better for smokers and in particular our e-cigarette portfolio and Blu is a very interesting and successful offering, helping smokers to switch."
