Natural History Museum's 'Dippy' replaced by whale

The Natural History Museum is to replace its long-time entrance hall exhibit of a Diplodocus dinosaur in a bid to increase visitor numbers.

The exhibit, nicknamed 'Dippy', will be exchanged with the giant skeleton of a blue whale, in an attempt to get visitors to think more of the the future than the past.

After its removal, Dippy will be taken on a tour around Britain, as Richard Lister reports.
