What's in the Cheesegrater? From Aon to Amlin, here's a storey-by-storey breakdown of every business in the Leadenhall Building

It may not be London's biggest building - but the Leadenhall Building, aka the Cheesegrater, still remains one of the tallest skyscrapers in the Square Mile, towering over its neighbours the Gherkin and the Walkie Talkie.
The 225 metre building's characteristic tapered design was created to preserve views of St Paul's Cathedral.
Ever wondered what's going on inside? We've put together a storey-by-storey breakdown of every occupier in the building, from Aon at the bottom, to FM Global's record-breaking letting on the 41st floor.
