A Bermuda-registered private jet airline has been ferrying UK opposition politicians, including would-be Prime Minister David Cameron, across the globe, clocking up 184,000 miles of travel in the past year.

The Conservative Party MPs have travelled to various corners of the world thanks to private jet airline Flying Lion, which is owned by millionaire Lord Ashcroft.

The company is registered at Cedar Avenue in Hamilton. It hit the headlines in the UK newspaper The Guardian with reports that shadow cabinet ministers, including leader of the opposition Mr. Cameron, had been enjoying the use of a luxury jet Dassault Falcon 900EX to make trips to Israel, China, Mali and the Czech Republic.

The reports were based on information in the Parliamentary Register of Interests and declarations to the Electoral Commission.

According to the statistics, 32 trips covering a total of 184,000 miles have been made over the past five years, with shadow international development secretary Andrew Mitchell accounting for 65,453 of those and shadow foreign secretary William Hague 49,670.

Research by The Guardian revealed the Opposition party's globetrotting has produced 1,289 tonnes of carbon emissions, with Michael Ancram having the biggest carbon footprint during his time as shadow foreign secretary and shadow defence secretary, according to environmental consultants Carbon Footprint, with emissions of 372 tonnes for excursions to Cuba, Afghanistan, Egypt and Poland.

Flying Lion's Falcon 900EX allows its MP passengers to travel in comfort and style, with features such as "supple leathers, glistening veneers and deep pile carpet as standard", according to its French maker, Dassault.

It boasts a galley that houses "all the essentials for a fine dining experience 45,000ft in the air", with a 7ft wide cabin "so you can move easily with your head held high".

The Falcon uses about 3,000 US gallons of fuel to fly 4,000 to 5,000 miles, compared to a Boeing 777, which uses about 30,000 US gallons to cover the same distance carrying up to 300 people, where the latter can significantly reduce its carbon footprint per passenger kilometre, the usual yardstick for emissions.
