'£1bn pledged' for cycling and walking routes across England

Johnson told MPs figure was 350m but sources say he made error in 'car crash of an announcement'

The government has earmarked 1bn for safe cycling and walking routes in the next five years - not 350m, as Boris Johnson mistakenly told parliament in what one expert called "a car crash of an announcement", the Guardian has learned.

But 1bn is still not enough to even build Greater Manchester's 1,800-mile Bee Network of safe paths, according to its architect, Chris Boardman, a former Olympic cycling champion who is the region's walking and cycling commissioner. He has asked Johnson for 1.2bn and says he will continue to do so.
