Shard to overtake Canary Wharf

After almost 20 years - Canary Wharf's about to lose the title of Britain's tallest building.

The Shard - currently being built by London Bridge station - is expected to take the title in the next week.

When it's finished in 2012 it'll be the tallest building in Western Europe with 87 floors and more than 1000 feet high.
