IEA Director of Lifestyle Economics Christopher Snowdon spoke to BBC Five Live Morning Reports regarding the Labour Party's proposals to ban smoking in cars with children in. In the interview he argued that the implementation of such legislation would be a gross infingement of property rights. Furthermore, it sets the precedent of what individuals can and cannot do, it also allows the possibility to extend such legislation into domestic homes.
Furthermore he argued the issue seems to be rather trivial, with only 14 percent of parental smokers who would actually smoke with a child present in a car and the legislations seemingly unenforceable should it be implemented.
