London Mayor Sadiq Khan is to take over control of the London Stadium, after an independent review revealed “a catalogue of errors” leading to massively increased costs during the stadium’s conversion after the London 2012 Olympics.

The review, published yesterday, called the conversion a “bungled decision that has left the taxpayer to foot an annual loss of around £20 million.”

Mr Khan said: “I ordered the review into the finances of the London Stadium to understand how key decisions were made about its transformation and why costs were allowed to spiral out of control.
