A painting by former British prime minister Sir Winston Churchill, which was owned by Angelina Jolie, has sold for £7m at auction in London.

Axar.az reports that the sale price was almost four times the top pre-sale estimate and beat the previous record for a Churchill painting, which was just under £1.8m.

The Tower Of The Koutoubia Mosque, painted in Marrakesh during World War Two, was sold to an anonymous buyer.

A Christie's spokesperson called it "Churchill's most important work".

"Aside from its distinguished provenance, it is the only landscape he made during the war," the spokesperson added.

Churchill, a keen artist, took inspiration from the Moroccan city and painted The Tower Of The Koutoubia Mosque oil work following the Casablanca Conference in 1943.
