It could soon be illegal to smoke in a car where a child is present if new legislation clears the House of Lords.
Labour is proposing an amendment to the Children and Families Bill, which would make smoking around children a specific offence, according to the BBC.
Under these plans, it would be an offence for drivers of private cars to fail to prevent smoking on journeys whenever a child is present. Smoking was banned in workplaces and enclosed public spots in England in 2007.
Andy Burnham, Labour's shadow health secretary, said Britain should follow the example of several US states, as well as Australia and Canada. He said that officials are "duty bound" to protect and improve the health of children.
He said that adults are free to make their own choices when it comes to health, but children are not - "and that's why society has an obligation to protect them from preventable harm".
Mr Burnham added that evidence shows that stopping smoking in cars carrying children can protect their health, and that the measure has "strong public support" as it goes before peers.
