MADRID, Aug 6, 2007 (AFP) - Fernando Alonso says he is uncertain about his future at McLaren after his relationship with teammate Lewis Hamilton reached rock bottom at the Hungarian Grand Prix over the weekend.

The two time world champion, asked by Spanish sports daily Marca if he was planning to stay with McLaren, replied: "I don´t know."

The paper reported that Alonso´s father, Luis Garcia-Abad, who also acts as his agent, held talks with Renault boss Flavio Briatore after Sunday´s race won by Hamilton.

The French team, for whom Alonso won his two world titles, are keen to resign the Spaniard who is also reportedly being wooed by BMW.

Alonso had to settle for fourth after being demoted five places from pole for holding up Hamilton in qualifying on Saturday.

McLaren said the delay at the pit-stops in qualifying was Hamilton´s fault, for causing confusion in the team by disobeying an order to let Alonso pass him ahead of the pit stops.

But the FIA, Formula One´s governing body, did not agree, and imposed a penalty on Alonso, as well as docking McLaren the 15 constructors´ points they earned from the race.

Hamilton said after the race which left him seven points clear at the top of the drivers´ standings that Alonso had cold shouldered him since the incident.
