West Ham have been granted permission to go ahead with their plans to redevelop the Olympic Stadium.
Plans for the conversion of the Stratford site to a 54,000 all-seater stadium were ratified at a Planning Committee meeting on Tuesday evening.
The plans include the installation of retractable seating on all four sides of the stadium to bring the fans closer to the pitch and a transparent roof.
"This is another key milestone on our journey to Stratford and my Board and I are delighted with the decision," vice chairman Karren Brady told the club's official website.
"We always knew that the innovative plans for the Olympic Stadium could create a globally-recognised football stadium and we were confident that planning permission would be granted to allow the conversion work to begin.
"For me and my team the hard work is only just beginning. This is an incredible opportunity to create a world-class stadium for West Ham supporters that will exceed their expectations and the chance to really deliver a lasting legacy for London."
