Formula One boss Bernie Ecclestone wants to extend his double-points scheme to the last three races of the season.
The new format, which has been criticised by fans, teams and drivers, has been introduced for the final grand prix of the season in Abu Dhabi.
Now Ecclestone has written to the teams saying he wants to extend it to the two preceding races, in the USA and Brazil.
He needs unanimous approval for his proposal to go ahead, as a number of teams have reservations about it applying even to one race after the uproar it has caused, The BBC reports.
Ecclestone's plan is to increase the chances of keeping alive the battle for the F1 title until the final grand prix of the season.
