A recently discovered painting by wartime prime minister Sir Winston Churchill, entitled View of Tinherir, has been sold for £612,800 at auction.
Sir Winston Churchill painted for relaxation
The oil picture, which was painted in 1951 while Churchill was in Morocco, was expected to fetch about £250,000.
It was sold at Sotheby's by Kitty Winn, granddaughter of US General George Marshall, to whom Churchill gave the painting as a gift in 1953.
The price tag is a record for an artwork by the former prime minister.
A Sotheby's spokesman said the next most expensive Churchill painting sold was On The Rance, Near St Malo, which fetched £344,000 at auction last year.
"It's quite a rare event for something like this to just pop up out of the blue," said Sarah Thomas of Sotheby's.
"With such an amazing provenance - it was given to one of the most historic families - it's all the more remarkable that it was missed," she added.
Churchill visited Marrakech in Morocco frequently to compose his war memoirs and to paint.
It is in Morocco in 1943 that Churchill first met General Marshall, who was US President Franklin Roosevelt's army chief of staff during World War II.
Churchill came to revere the general as "the last great American" and he promised one day to pay tribute to his work training the US forces.
Ms Thomas said: "Churchill took up painting very late. He saw it as a hobby, he didn't see himself as a professional painter. It was something that he really loved doing.
"Most importantly, he found relief from all the pressures of his work in his painting. It was quite a therapeutic act. He would paint while mulling over speeches and decisions.
"His work does vary in quality, everyone would acknowledge that. A lot of his paintings are pretty poor and amateur and full of splodges.
"But over the years he learnt quite a lot from his artist friends. In his later work you can see that."
Two paintings by Churchill were recently sold for more than £300,000 each at auction.
