Public Health

Can the shadow Minister cast his mind back to the debates we had on smoking in public places? If he is suggesting properly engineered extraction ventilation, we dismissed that during those debates�although many of us would have liked to have seen it as an alternative to an outright ban�because of the sheer engineering cost of doing it. Or is he proposing simply opening windows? What exactly is he proposing when he says we need to improve ventilation? At one extreme it is going to be murderously expensive and virtually impossible, and at the other it is simply opening the window.
