The first electric black taxis have arrived on the capital's roads as the London mayor pushes to improve air quality.

It is hoped more than 9,000 of the £55,599 cabs will be in service by 2021.

The TX can travel 80 miles on a single battery charge and is fitted with a 1.5 litre petrol engine to assist longer journeys. The cab has six seats, contactless card machines, Wifi and USB charging.

The London Electric Vehicle Company (LEVC) says it will save drivers on average £100 in fuel a week.
