One of London's most recognisable landmarks, the Gherkin, has been put up for sale and is expected to be snapped up by an overseas buyer.

The 40-storey City of London skyscraper was put into receivership in April, and the agents appointed to sell it are hoping for offers in the region of £600m to £650m. Savills and Deloitte Real Estate have been jointly instructed to sell the 505,000 sq ft (46,900 sq m) office building, which was designed by Lord Foster and opened in 2004. The two firms said marketing of the Gherkin – including an advertising campaign and a dedicated website – was about to begin, "with interest expected to come from all corners of the globe."
