So is the ban on smoking in cars with children, backed by MPs this evening by 376 votes to 107 against, a good idea? As James observed earlier, it is fascinating to see how quickly opinions have shifted even in the past few weeks. The PA division lists have 100 Conservative MPs voting against, and only four Liberal Democrats opposing a ban that their own leader described as ‘illiberal’.

But it is worth reflecting that the Cabinet ministers who voted against it included Theresa May and Chris Grayling (the others were Iain Duncan Smith and Theresa Villiers). Grayling was voting reluctantly on the basis that the ban was unenforceable. Which given he’s the Justice Secretary, doesn’t inspire great confidence about the legislation, regardless of the principle.
