Ms Porter, a Camden resident, said she gave up her ‘gas guzzler’ years ago and is now to be seen driving around London on a tandem bicycle with her young daughter.

She said: “I’m here to support the Green Motor Expo … the idea of this show is to show that cars, vans and bikes are changing right now with lots of vehicles entering the market place.

“I’m also here to endorse Camden Council’s Green Promise scheme, which I’ve just signed up with.

“I ditched my gas guzzler a wee while ago, because I just thought it was useless to have these things and obviously I want to do my bit for the environment.”

The show featured some of the latest examples of environmentally friendly cars, vans, scooters and bicycles from a number of companies.
