What was the choice facing MPs?
Option 1: Essentially this was Labour's manifesto pledge to introduce a ban on smoking in all enclosed public places in England, except pubs which do not serve food, and private members' clubs. It was the option agreed last autumn by Cabinet after protracted debate. Championed by ex-health secretary John Reid.
Option 2: A complete ban on smoking in all enclosed public places, including all pubs and private clubs. This was the option the current Health Secretary Patricia Hewitt voted in favour of, after a consultation suggested Option 1 might be unworkable and make health inequalities worse. Championed by health minister Caroline Flint.
Option 3: A complete ban on smoking in all enclosed public places, except for private clubs. This offered another option to MPs facing anger from private clubs, such as Labour/Conservative clubs, working mens' and golf clubs at having a ban imposed on them.
Where will smoking be banned?
Smoking in all public places like pubs, cinemas, offices, factories, public transport and so on will be banned.
Where will you be able to smoke?
People will still be able to smoke outdoors, and in private homes, plus places that Ms Hewitt says are "like homes", such as care institutions, army barracks, and prisons.
When would a ban come into force?
Summer 2007.
I take it that this means OPTION 2 is what has won.
