A traffic jam is seen as cars head towards the approach tunnel of Heathrow Airport, west London
A file photograph shows a traffic jam as cars head towards the approach tunnel of Heathrow Airport, west London, Britain November 26, 2015. London transport bosses decided on Wednesday not to impose a series of strict new rules on private hire cars, including those from apps like Uber, but could make such services pay a daily charge for entering the city centre.
