Car smoking ban edges a step nearer

I shall be on LBC tonight responding to this story:

Peers back smoking ban for cars with children present (BBC News)

I have also been told that, "The topic of smoking in cars featured on LBC earlier this morning and every caller, text, email was against the idea of a ban. A lot of reference was made to the police already having enough to do and banning smoking in cars was unenforceable".
