Enterprise Inns is expected to announce this week that poor summer weather and cost increases have slowed growth across its 5,200-strong estate. The company is also keeping an eye on the debate over smoking in public places. It recently announced plans to ban smoking in around 80% of its trading space by 2009. Pernod Ricard is expected to announce strong first-half results this week because the weather has less effect on consumption of spirits and wine.
