Shares in pub chains slumped last week as investors grew nervous ahead of next Sunday's smoking ban. City analysts said the impact, coupled with fears about a forthcoming government review into alcohol prices and promotions, was being felt across the whole leisure industry. Enterprise Inns share price fell 17.5p to 674.5p, while Punch Taverns dropped 20p to 1272p. Brewery companies Scottish & Newcastle and SABMiller were also hit.
