Piquet Dropped By Renault, Slams Briatore

`I have received notice from the Renault F1 team of its intention to stop me from driving for them in the current F1 season,` Piquet said.

Nelson Piquet delivered a furious parting shot to Renault boss Flavio Briatore on Monday after discovering he was being dropped by the Renault team.

Piquet described Briatore, his manager as well as the team boss, as his "executioner" as he announced he would no longer be driving for Renault in the 2009 Formula One season.

"I have received notice from the Renault F1 team of its intention to stop me from driving for them in the current F1 season," Piquet said in a statement.

"A manager is supposed to encourage you, support you, and provide you with opportunities. In my case it was the opposite. Flavio Briatore was my executioner," Piquet said of Briatore.

The 24-year-old, son of triple world champion Nelson Piquet, had not scored a point all season.

Piquet said in his statement that in his 2008 debut season, racing alongside team mate and double world champion Fernando Alonso, he was relegated as "someone who drives the other car".

The Brazilian said that circumstances did not improve this season despite promises by Briatore for "at least equal treatment".

"The conditions I have had to deal with during the last two years have been very strange to say the least -- there are incidents that I can hardly believe occurred myself," Piquet said.

"I feel a sense of relief for the end of the worst period of my career, and the possibility that I can now move on and put my career back on the right track and try to recover my reputation of a fast, winning driver," he added.
