Alex Salmond facing second inquiry into SNP donor links Labour last night asked for another inquiry into whether Mr Salmond has broken the ministerial code of conduct, in addition to an ongoing investigation regarding his dealings with a couple who won Europe's largest ever lottery jackpot. The Daily Telegraph revealed last week how Chris and Colin Weir donated £1 million to the SNP four days after Mr Salmond invited them to an undisclosed tea party at Bute House. The event was not included in the official register of the First Minister's at the Georgian town house despite his senior spin doctor insisting all names were "proactively published." Paul Martin, Scottish Labour's parliamentary business manager, said the SNP had given three different excuses for not releasing information about their dealings with Sir Brian. "The longer Alex (Salmond) desperately tries to keep these documents secret, the more people will think he has something to hide," he said. He said the First Minister had "abused his office in exactly the same way as David Cameron abused his" by inviting the Watsons to the Bute House lunch, held on July 1 last year to mark the opening of the Scottish Parliament. The Souter controversy has echoes of Mr Salmond's decision to go to Scotland's highest civil court twice to prevent this newspaper seeing documents showing his local income tax would cost households 50 per cent more than he claimed. Kevin Dunion, the recently-retired information commissioner, ruled SNP ministers acted unlawfully but they have now insisted they cannot release their correspondence with Sir Brian because it would cost more than the legislation's £600 limit. David McCarthy and his wife were among eight guests for a dinner at Bute House following the Queen's Royal Garden Party at Holyrood Palace in July 2010. The Weir meeting emerged the day after Mr Salmond wrote a letter to David Cameron criticising him over the Prime Minister's "cash - for - access" scandal. Unlike the lottery winners" tea party, the other donors" meals were included in the public register. A spokesman for the First Minister said: "No private dining for donors takes place at Bute House, never has under this administration, and never will."
