Barclays' Roger Jenkins - paying 40% income tax?

Well, it appears that Barclays' "£10 billion of tax payments" that CEO Varley claims they've paid in the last five years includes anything and everything they can loosely construe as tax payments, the bulk of which is probably their employees' income tax. Odd, I'd always thought that I was paying my income tax, rather than my employer. But for an organisation so familiar with the concept of double dipping, such technicalities are obviously fatuous.

Re Barclays' Roger Jenkins, the "Roger the Dodger" who masterminds their tax avoidance schemes, I'd love to know what percentage of his reputed £40 million salary is paid as income tax?
