MPs have backed a plan to ban anyone born after 2009 from buying cigarettes, effectively ensuring it will become law. The measures, championed by Prime Minister Rishi Sunak, survived despite opposition from several leading Tory figures - including two ex-PMs. Health Secretary Victoria Atkins told MPs "there is no liberty in addiction" as she defended the plans. The Tobacco and Vapes Bill passed by 383 votes to 67. If they become law, the UK's smoking laws will be among the strictest in the world. The UK's approach is thought to have been inspired by a similar law in New Zealand, which was later repealed after a change in government. Tobacco use is the UK's single biggest preventable cause of death, killing two-thirds of long-term users and causing 80,000 deaths every year. The bill also aims to make vapes less appealing to children, with new restrictions on flavours and packaging. Trading standards officers would also get new powers to issue on-the-spot £100 fines to shops selling tobacco or vapes to children, with all the money raised going towards further enforcement.
