Gus O'Donnell, in 2009, is listed as earning £285K per annum.
And from an article in the Independent last year, ( after the BrokeBack coalition took office ) - "He was appointed Permanent Secretary to the Cabinet in 2005, with a salary of £240,000. He will have a lump sum of £305,000 and an income of £105,000 a year when he retires". ( http://www.independent.co.uk/news/uk/politics/gus-odonnell-to-quit-before-next-election-2049100.html )
