Scotch whisky distillers unveiled strong export figures for 2003 on Thursday, a welcome boost as the industry gears up for a wrangle with the Treasury over plans to cut down on smuggling by the introduction on tax stamps. Exports rose 4% to £2.37bn, a figure within £20m of the record high recorded in 1997. Volumes were up by a similar amount, to 981m bottles. Ian Good, chairman of the Scotch Whisky Association, said the industry's contribution to the UK economy would be damaged by the introduction of tax stamps.
