Bribes.
BAe are having to roll with the punches at the moment as the Saudis, and I know this may be hard to believe, are becoming much more financially astute. Profit margins are becoming tighter as the Saudis now realise just how much they have been milked by BAe over the years and are now calling the shots in the current contract negotiations. Difficult times for anyone caught in the middle and I suspect that the AVM will have had his hands full!
BAe's days of taking their place in KSA for granted are running out. They are going to have to be much more competitive, value for for money and transparent in business if they want to survive over there...
