Titian's Diana and Callisto saved for nation

Here's my report on the latest addition to the national collection - Diana and Callisto, by the Renaissance master Titian.

It has been bought for the British people by the National Galleries in London and Edinburgh, after a £45m ($71.7m) deal was agreed with its owner, the Duke of Sutherland. Diana and Callisto is a companion piece to Diana and Actaeon; that was purchased from the duke for £50m in 2009, following a national fundraising campaign.

Both paintings, on public display in London for 18 months, will move to Edinburgh and then rotate between the galleries.
