The statements from Scotch Whisky Association chief executive David Frost represent the first time the SWA has publicly responded to concerns that the industry might be capable of delivering more tangible benefits to the Scottish economy (Scotch whisky is our darling, Letters, July 26). Clearly the SWA will move heaven and earth that the motion doesn't make it on to the SNP’s conference agenda, as you previously reported (Activists pushing SNP Government to challenge dominance of big firms in Scotch whisky industry, Business, July 19).

The claim the industry “adds £4.7 billion of value to the Scottish economy” is just as often expressed by the SWA as “adds £4.7 billion of value to the UK economy”. It depends on the audience. Big Booze is no different from Big Oil, Big Energy, Big Pharma or Big Tobacco in its ability to multiply their alleged contribution over several different constituencies.

But when the SWA fails to specifically rebut claims that 83% of the industry is owned or controlled from outside Scotland; when it ignores statements from as eminent an economist as Professor John Kay that only 2% of the global revenues stay in Scotland and when it refuses to counter the fears of industry experts that 98% of its claimed £1.4 billion annual supply chain spend goes to suppliers owned outwith Scotland, then its integrity and loyalty to Scotland is cast into doubt.

As a former Diageo executive and one of the "10,000 Scots" Mr Frost said had "work(ed) hard to ensure that Scotch whisky retains its position as the world’s leading high-quality spirit drink”, it sticks in my craw to hear the economic benefits of this world-renowned Scottish asset, which other countries would give their eye-teeth for, so undervalued by its own trade association.
