There are currently two electric car charging points in London

The two points, supplied by Westminster City Council, are in Wellington Street and Southampton Street near Covent Garden in the West End.

They will join 48 free charging stations to be found in 13 of the council's car parks.

A spokesman said they were being introduced because electric cars were "ideally suited" to city driving.

London, and particularly Westminster, has well documented problems with air quality and electric cars are an excellent way to start dealing with that Councillor Alan Bradley

Councillor Alan Bradley said: "Putting free charging points on the street where people need them most is a simple concept which we hope will help galvanise broader appeal for electric car use.

"Electric cars are ideally suited to city driving and we hope in years to come we will see more and more people using them to travel around the City of London.

"London, and particularly Westminster, has well documented problems with air quality and electric cars are an excellent way to start dealing with that."

According to Westminster Council, Westminster has the UK's highest levels of air pollution because of the amount of daily traffic coming in and out of central London.

Electric vehicles have zero emissions and are exempt from the congestion charge.

More than 750 G-Wiz vehicles have been sold in London - a third of them in the last six months.
