'London's most expensive apartment' on sale for £150 

It's just a short hop from Buckingham Palace and has been home to such luminaries as Sir Winston Churchill and Lord Mountbatten.

Now, a flat has become available for sale in Admiralty Arch for an estimated £150 million.  The apartment is believed to be the most expensive ever put on the market in London after topping One Hyde Park, at £140million, the Telegraph reports.

The flat comes with six-metre high ceilings, extravagant cornicing, original fireplaces, a concierge service, off-road valet parking and lifetime membership of a private members' club.

It is being sold by Spanish developer Rafael Serrano, who bought a 250-year lease of the building from the Government in 2012 for £60m. He is also turning the site into a luxury hotel.
