PARIS: Nelson Piquet has been sacked by Renault after failing to pick up any points for the French team this season, the 24-year-old Brazilian announced on his personal website on Monday.

Piquet, without a win in 28 races, said in a strongly worded statement that he was disappointed at losing the drive and criticised his treatment by Renault supremo Flavio Briatore.

He described his time with Renault as the worst period of his career and said he now wanted to start afresh and prove his driving credentials with a new team.
