The smoking ban was voted against by most Tory MPs, so it is no surprise that right-wingers like Johnson want it repealed. Boris gives us an insight to what a future Tory government will be like.
The smoking ban is probably the single most effective legislation that will improve people's health over generations since Labour set up the NHS.
If you like the ban and want to save your lungs then vote for Ken. Boris must be stopped.
If you think this is a civil liberties issue (it isn't) and if you think Boris is some sort of libertarian, remember that he also wants to ban drinking alcohol on the tube.
*update* It seems Boris's minders are now typically trying to deny the whole thing - Boris just cannot control his tongue - imagine this guy trying to promote London - what a mess!
