One of the biggest art auctions in history, taking place in New York, has been marred by controversy.
Andrew Lloyd Webber bought the painting for $28m in 1995
A 1903 Picasso painting, which was to have been auctioned by Sir Andrew Lloyd Webber, has been withdrawn at the last minute due to its Nazi-era history.
A descendant of a previous owner claims his ancestors were forced by the Nazis to sell the painting in the 1930s.
The piece, Portrait of Angel Fernandez de Soto, was predicted to fetch up to $60m (£31.5m).
The auction had been touted as a once in a lifetime art sale by Christie's auction house.

Julius Schoeps, an heir to Berlin banker Paul von Mendelssohn-Bartholdy, says his ancestor had to sell the Picasso at a low price after he was forced to flee his mansion during the 1930s.
But it is not the only painting in the sale with a Nazi connection. All eyes are on four paintings by Gustav Klimt, the Austrian artist, which were at the centre of a Nazi restitution case earlier this year.
That case was resolved to the satisfaction of the owners, who have now put these masterworks up for auction. They are predicted to go for more than $100m.
Another Klimt from the same group fetched the highest price ever paid for a painting when it was sold in June. New York's Neue Galerie is reported to have paid $135m for Klimt's Portrait of Adele Bloch-Bauer.
