Piquet wants son free from Briatore

Nelson Piquet Snr is threatening to take Flavio Briatore to court in the hope of extricating his son from the deal in place with the disgraced Renault team boss.

Despite the ’crashgate’ scandal that resulted in Briatore resigning from his position on Wednesday, and Piquet Jnr becoming virtually unemployable, the Italian still manages the young Brazilian.
