Webber to Williams, I'm not too surprised about, but Fisichella to Renault is a bit questionable. Apparantly Jarno Trulli jumped ship because Flavio Briatore was putting the squeeze on him looking for a management contract. Despite Briatore's claims to the contrary, it couldn't have been anything to do with lap times etc...as Jarno has been as quick as Alonso all year, quicker on a lot of occasions.
Renault should give Briatore the bullet in my view. He doesn't add much to the team. He is not a motor racing man, nor a technical man, doesn't decide strategy or anything like that. But he does go to all the right parties.
His main interest seems to be tying up drivers on long term management contracts and then using his position at Renault to move them around to his best advantage. Take this week. Williams wanted Fisichella, but Flavio decided that if Webber was going to Williams, then he wanted Fisichella. Webber is under contract to him also. Its a bit tricky this, but Fisi's contract at Sauber had a buy out clause stating that he could leave for one of McLaren, Williams or Ferrari, the reason he is at Renault now is because that "Webber's manager Flavio Briatore took advantage of this situation by blocking the Australian's move to Williams unless Frank Williams agreed to negotiate a release for Fisichella from Sauber" - from GrandPrix.com.
You don't see Frank Williams, Ron Dennis or Jean Todt getting involved in this kind of silliness. Flavio is a leech on the back of F1 and anything Renault have achieved (not much) they have achieved in spite of their team director.
They should lose him to make the next step.
