Plans for a new London skyscraper dubbed the Tulip have been turned down by London Mayor Sadiq Khan.
The proposed development, on land at 20 Bury Street, would have become the second tallest building in Western Europe after the Shard and stood at 305.3 metres high.
The City of London Corporation rubber stamped an application from Brazil's J Safra Group and Foster + Partners for the development in April, but Mr Khan said the Tulip would not "constitute the high standard of design required for a tall building in this location".
"The proposal would compromise the ability to appreciate the outstanding universal value of the Tower of London... and would cause harm to the historic environment, the wider skyline and image of London, strategic views as well as the public space surrounding the site.
"The public benefits of the scheme are limited and would not outweigh this harm," Mr Khan said.
The Corporation's Planning and Transportation Committee voted by 18-7 to approve the project, despite concerns that it could impede views of London. J Safra also owns London's Gherkin, on land adjacent to the proposed Tulip site.
