A TOWN crier is calling on people to leave their cars at home as part of a clean air campaign.

Nancy Buckle, of Knaresborough, will shout out her green message to visitors tomorrow as part of national Don't Choke Britain Day.

Ms Buckle is one of 100 town criers throughout the country chosen to spread the word that drivers can make a difference to the environment, even by taking a short walk to the shops or postbox.

A keen walker, she said: "I can drive but I don't have a car, so I let my boots do the walking.

"I'm a great walker, always have been, and I passionately believe that if people used their cars just a little bit less, particularly for short trips, it could make a difference."

Ms Buckle will deliver her message in the grounds of Knaresborough Castle at 11am, with a backdrop of the town's famous railway viaduct crossing the River Nidd.

She said: "I can't think of a more appropriate place in the town. It's a famous view, but trains crossing the bridge demonstrate there are other ways of getting about without the car."
