London’s cycle network overhaul has come to a standstill

Sadiq Khan's claims to have built 140km of cycling infrastructure are simply false

Among the more amusing frauds of the energy company Enron was the time, in 1998, when it decided to create an entire fake trading floor at its Texas HQ - complete with TVs, computers, and shirtsleeved guys shouting down phones - to fool Wall Street analysts visiting for its annual general meeting.

Now, however, the mayor of London, Sadiq Khan, appears to be aiming for something even more ambitious - an entire fake cycle network. I am in south-west London, in an alley about six feet wide, wedged between a railway line and the back garden fences of Southdown Road. According to Khan, this is the Wimbledon to Raynes Park Quietway, part of the 140km of cycle infrastructure, which he claims to have built since taking office.
