Analysts expect Diageo this week to announce flat year-on-year operating profits. Interim numbers revealed underlying profits were up 3% but Diageo warned that dollar weakness would have a greater impact in the second half. Volume growth for the bigger brands is likely to be around 10% in total for the year, although the popularity of alcopops ú or "ready-to-drinks" ú continues to wane.
