High salaries for public sector bosses have been criticised by the Conservatives as "crazily out of kilter" with frontline staff.
The Tories criticised the discrepancy between bosses and staff salaries
The average pay of the top 10 earners is about 40 times the starting salary of a nurse, research by the Taxpayers' Alliance suggests.
Ex Tube boss Bob Kiley, Royal Mail chief Adam Crozier and Network Rail's John Armitt get more than £1m a year.
Shadow minister Alan Duncan said pay should reflect "competence and risk".
The highest paid person on the Taxpayers' Alliance "public sector rich list" was former Transport for London boss Bob Kiley, earning £1,146,425. He left the job in January this year - three years earlier than expected.

The prime minister was listed at number 88, earning £186,429.
Mr Duncan, the shadow trade and industry spokesman, said: "When Bob Kiley is paid nearly ten times more than the prime minister, then the world has gone mad.
"People should be rewarded for their competence and the risks they take. A lot of these payments seem crazily out of kilter."
The other two £1m-plus earners on the campaign group's were Royal Mail's Adam Crozier and Network Rail chief executive John Armitt.
The alliance said the average salary of all those on the list was £259,701.
For the top 12 earners in the NHS, the average salary was £183,000 - compared with a starting salary for a nurse of about £19,000, it said.
Shadow chief secretary to the Treasury, Theresa Villiers, said: "If we're going to get good value for money for the taxpayer and ensure public spending is focused effectively on delivering front line services, the chancellor has to take a much tougher line on quangos and bureaucracy and he shouldn't be shelling out for million pound salaries."
The Taxpayers' Alliance, which counts Conservative donors Sir Anthony Bamford and Stuart Wheeler among its backers, was formed in 2004 to mobilise grassroots pressure for lower taxes.
It used information about salary, bonuses, incentive plans, benefits-in-kind and pension contributions, where applicable, as recorded in official publications, to compile its list.
