Hundreds of thousands of children could be saved from being exposed to second-hand smoke in cars after MPs paved the way for legislation which could see an end to the practice.
Leading medical charities have said they are “delighted” that MPs voted in favour of outlawing smoking in vehicles carrying children in England.
The Commons have given the health secretary the power to impose a ban despite the opposition of some MPs, including members of the Cabinet.
Ministers were granted a free vote on the measure – successfully introduced by Labour in a House of Lords amendment to the Children and Families Bill – meaning they are not tied to a party line.
Dr Penny Woods, chief executive of the British Lung Foundation, said: “Having campaigned on this issue for many years, we’re absolutely delighted that MPs have backed the ban on smoking in cars carrying children.
“This could prove a great leap forward for the health of our nation’s children.
“The introduction of a law that would help prevent hundreds of thousands of children from being exposed to second-hand smoke in the car is now within reach.
“With both Houses of Parliament having made their support for the ban clear, the onus is now on the government to act accordingly and make this crucial child protection measure law at the earliest opportunity.”
Prime Minister David Cameron missed the vote while visiting flood-stricken areas.
His official spokesman declined to say which way the prime minister would have voted had he been able to attend Parliament.
Health Secretary Jeremy Hunt was in favour of the move while Justice Secretary Chris Grayling was in the “no” camp of those who said it is unenforceable.
