Do as the great and the good tell you

I wonder if anyone will actually think the following:

The Chairman of Tesco (chartered accountant and Old Fettesian) is worried that, if an SNP Government is elected, its pursuit of independence will de-stabilise business and hamper economic growth. Therefore I shall not vote for an SNP candidate as I would otherwise have done. Instead I shall vote for a unionist party.

It does not seem very likely. So why go through this charade of parading businessmen in the yellow press?
