Motorists who enjoy a cigarette behind the wheel may soon have to ensure their vehicle is child-free before lighting up.
That's after proposals to ban smoking in cars with children present took a step closer after the House of Lords voted in favour of an amendment to the Children and Families Bill.
The move, proposed by Labour, was backed by 222 votes to 197.
If the proposed legislation eventually becomes law, those caught smoking in a car with children will be risking a fine.
The proposed law will now return to the House of Commons where Government sources suggest MPs will be given a free vote on the issue.
Following the vote, shadow public health minister Luciana Berger said: "The Government should accept that tonight's defeat sends a clear message - we need action to put children's health first.
"When it comes to the Commons next month, Ministers, as well as Tory and Liberal Democrat MPs, should show they recognise that this issue cannot be ignored and not try to kick it into the long grass."
