Leak that won't raise a squeak of protest

City diarist Martin Waller puts his finger on the difference between corporate whistle-blowing and corporate leaking. He writes: "Some absolute rotter has gone and leaked to another newspaper the details of a backdown by Marks & Spencer on its proposed changes to redundancy terms for staff. M&S is taking disciplinary action against an employee who leaked news of the original plan. Will there be a similar witch-hunt over who sent out the more favourable story? Somehow I doubt it."
