The BBC reports Simon Hughes’ criticism of the Government for letting the plane take the strain a little too often.
Party spokesman Simon Hughes said: Government staff should “use trains and video-conferencing more so they fly around the country less”.
“Civil servants are spending staggering amounts of taxpayers’ cash flying around the UK,” he added.
“The Civil Service Code needs to change so that environmental factors are considered when travel bookings are made.”
Government departments spent £21.8 million on over 210,000 internal flights in the year 2008-9. Well over half that total is down to the MOD, with the Department for Work and Pensions coming in as the second highest spenders. The Department for Energy and Climate Change paid for over a thousand internal flights in the year.
