LONDON — Renault says managing director Flavio Briatore and engineering chief executive Pat Symonds are leaving the Formula One team, and that it will not dispute charges that Nelson Piquet Jr. was ordered to crash in a race.

Renault has been summoned to Paris by governing body FIA to answer a charge that Piquet Jr. was told to crash at last year’s Singapore Grand Prix to improve teammate Fernando Alonso’s chances of victory. The Spaniard won the race.
Renault said Wednesday it “will not dispute the recent allegations made by the FIA concerning the 2008 Singapore Grand Prix.”
The team added: “It also wishes to state that its managing director, Flavio Briatore, and its executive director of engineering, Pat Symonds, have left the team.”
