David Cameron flew in his brand new Prime Ministerial plane just once before his departure from office, it has emerged.

It was announced last year that former Mr Cameron would get an aircraft for himself and senior members of the Cabinet for their official trips.

An RAF Voyager A330 was to be refitted as a passenger aircraft at a cost of about £10 million, dubbed "Cam Force One".

But the customised jet only made its debut flight last week when the Prime Minister, Foreign Secretary and Defence Secretary boarded the jet to travel to the Nato summit in Warsaw.

And following Theresa May’s appointment to officer as the new Prime Minister, the aircraft is now under new ownership.

When the plane was announced last November, the government said it was a money-saving exercise, claiming it would save up to £775,000 a year on replacing charter flights currently used for long-distance trips abroad.

But the move, announced just a week before billion-pound cuts were revealed in the 2015 Autumn statement, received much derision.

Many claimed it locked the Government to a single wide-bodied aircraft, with a correspondingly massive carbon footprint.

Nonetheless others believed that compared with other governmental aircrafts in other countries Cam Force One was fairly modest.

Tony Blair had planned to buy two private jets when he was Prime Minister at the cost of about £100m, but it was scrapped by Gordon Brown, while the US President’s Air Force One cost £200m.

Now that Cam Force One is under new ownership, there is speculatuion as to what it will be called.

Patrick Kidd of The Times has suggested "May Fly (although that sounds a bit pessimistic)" or "ThereasyJet".
