Titian masterpiece Diana and Callisto saved for nation

One of the best known and most highly regarded Titian masterpieces has been bought for the National Galleries.

Diana and Callisto was saved for the nation after a £45m ($71.7m) deal was agreed with owner the Duke of Sutherland.

It will be displayed in London for 18 months before being moved to Edinburgh for a special exhibition marking the 2014 Commonwealth Games.

National Gallery director Dr Nicholas Penny said it was "an amazing opportunity" to acquire it.

The oil painting was bought with the help of £25m ($39.9m) from the National Gallery after a lengthy fundraising campaign.
