A mother has told the Victoria Derbyshire programme she will not obey a law that bans smoking in vehicles carrying children that has come into force in England and Wales.

Lucy Hardcastle told presenter Joanna Gosling she considered her car private property and her children would have to put up with it occasionally.

Drivers and passengers who break the law could face a penalty fine of £50 - but police say they will take a non-confrontational approach initially.

Whenever an under-18 is in the car, smokers will still be liable even if the windows are down or sunroof open.
