Fernando Alonso's second tenure at Renault is likely to end at the close of the current season, according to the latest reports from Spain.

The former world champion signed a one-year contract for 2008, with an option to automatically include 2009 should the French team reach certain performance targets by the British grand prix in July.

But with Alonso , 26, unlikely to be compelled to stay next year, the newspaper Diario Sport claims that he will shortly inform Renault bosses of his intention to move on - probably to BMW -Sauber.

The newspaper said Alonso must contractually either commit to Renault, or inform the team of his intention to leave, no later than July 31.
