The French on and offline casino group Partouche saw full year pre tax profits for 2007 halved, and prospects for 2008 impacted by the introduction of a smoking ban in France, saying the ban made the outlook for 2008 "uncertain." In a statement this week, the company said net profit fell to 14.3 million euro from 28.7 million euro a year earlier, on sales down 1 % at 854.8 million euro as new security checks kept some customers away from its French casinos.
