A Middle Eastern prince has bought a Ł300 million "flying palace".

Saudi Arabia's Saudi Prince al-Waleed bin Talal- has reportedly splashed out on the plane which, when completed in three years time, will be the world's largest private jet.

Plans drawn up by British firm Design Q for the airbus A380 show it will boast a marble-lined Turkish bath for four people, a fully-equipped boardroom with technology so advanced people not onboard can be virtually projected onto the table to 'join' a meeting, a concert hall complete with baby grand piano, and even garage for a Rolls Royce.

Design Q co-founder Gary Doy said: "It is something very, very special and there is nothing like it on the market yet. There is everything a billionaire could want.

"We are not trying to put a hotel in the air, it is tailored to the needs of flying, and has unique features which fit into that. The Turkish bath is particularly spectacular, a steam room with marble, low lights and lots of spa treatments to choose from."

There is also a wellbeing room, which boasts giant screens on the floor and walls that show the sky outside, giving guests the illusion they're travelling on a "magic carpet".

The luxury living quarters contain four poster beds, entertainment systems and computerised prayer mats which automatically face Mecca.

Flyers can disembark in style, using the lift which runs through the plane's three floors to the airport tarmac, where a red carpet will unfurl to "give the impression of turning up at the Oscars".
