Officials from London Councils and City Hall are due to meet this week to discuss the charter, which is slated to be unveiled in April.
At present, Transport for London , chaired by the mayor , manages 580km of main roads and all of London’s 4,600 traffic lights. While some roads are of pan London strategic significance, many borough leaders feel most trunk roads would be more efficiently controlled by them, ending the duplication of traffic wardens and maintenance services locally.
London Councils chairman Merrick Cockell (Con) said it would be beneficial if road control was simplified. He described the charter as “a flexible constitution rather than a list of demands”, providing leadership on areas including the economy and youth care.
A Labour source said: “When it has come to the crunch he has failed to properly consult the boroughs.”
