Worried about public health and the effects of passive smoking, ministers proposed a limited ban on smoking in restaurants and pubs serving food. But MPs had no patience for such nuances in a free vote on February 14th, they outlawed smoking from the summer of 2007 in all restaurants, pubs and clubs in England.
