One of London’s most iconic buildings, The Gherkin, in the heart of the city’s financial district has been put up for sale.

The skyscraper, which was designed by Lord Foster, opened in 2004. It is currently let to around 20 tenants, including Swiss Re.

Interest is expected from around the globe for the 40 storey landmark office building and offers in excess of £650 million are being sought.

The tower was placed in receivership in April by its creditors after one of its owners was placed in insolvency.

A dedicated website has been set up at www.gherkinlondon.com for interested parties to register by Saturday 16 August, with  the bidding process expected to end in September and closure by mid-October.
