MPs have raised questions as to how the ban on smoking in cars carrying children will be enforced, with some criticising the plans as a "nanny state" ban.
The Health Secretary will be given the power to impose a ban despite the opposition.
Smoking in cars is wrong, but a statutory ban? Who'll enforce it? Do we ban kids standing by fires next! I'm voting against it.
I voted No to the Ban. I totally support the principle but think it will be unenforceable. Education needed.
After much deliberation, I voted against nanny state ban on smoking in cars, I was in a minority, legislation is going to be interesting
