Speaking of the segregated lanes introduced between Stratford and Bow roundabout last week, a London Cycling Campaign spokesman said: 'The section of the Cycle Super Highway from Aldgate to Bow was terrible from the start. It was massively below the safety standards. Cyclist Claire Pepper was rescued from beneath a car after a collision in Spitalfields, East London, on Monday evening They promised to put in a segregated and semi-segregated lanes and we do welcome that, but there was no proposal for Bow Roundabout and from today's news we can see that this needs to be addressed.'

Brian Dorling, 58, was also killed on the roundabout in November 2011 in a separate accident. Witnesses today described the scene in Bow as 'a death trap'. Anika Bullock, 33, said: 'I was going to Tesco when I saw the ambulance, fire and police. 'I thought to myself "please don't let another person have died: not here again." The roundabout is a death trap. It causes me huge anxiety just to cross it. God knows what's it's like to cycle on it. Police have not made any arrests in connection with the incident.
