Bizarre race, Sunday’s Belgian Grand Prix. Force India very nearly won, thanks to the inspired efforts of Giancarlo Fisichella. Jarno Trulli qualified his Toyota on the front row. The BMWs finished fourth and fifth, while Jenson Button’s world championship prospects took another lurch down the rocky road to apparent oblivion when he crashed out on the opening lap.

Yet all these distinctly unusual elements were completely eclipsed by an announcement that the FIA was opening an investigation into events during last year’s inaugural Singapore Grand Prix which, if true, could lead to the most serious charges ever levelled at a competing F1 team.

The suggestion is that Nelson Piquet Jnr deliberately crashed his Renault on the instructions of his team in order to trigger a safety car deployment which would tactically advantage his team-mate Fernando Alonso who, indeed, did go on to win the event.
