Seven MSPs should today hang their heads in shame after they sold out Glasgow over the airport rail link.

The city’s SNP backbenchers feebly backed their party bosses – despite having once been its most enthusiastic supporters.

They lacked the courage of their previous convictions and were always going to fall into line with Alex Salmond’s orders.

Equally shocking but more surprising, were the Tories, supposedly the party of business.

The Scottish CBI , Glasgow and Scottish Chambers of Commerce, the Institute of Directors, the Federation of Small Businesses and the Scottish Council for Development and Industry all backed the rail link while the Tories didn’t.

Annabel Goldie and Bill Aitken have surely abandoned all hope of success in the west of Scotland, given they so readily sacrificed a project with 1300 jobs and hundreds of millions of pounds attached.

No wonder their vision for the nation is being questioned by their traditional supporters among Scotland’s business leaders.

But it is the SNP actions that have been the biggest disappointment, especially as some ministers have been willing to listen to Glasgow’s case on other subjects.

Alex Salmond, John Swinney, Nicola Sturgeon, Sandra White, Bob Doris, Anne McLaughlin and Bill Kidd have shown, when it came to the big issue they failed to deliver for Glasgow.
