Oct.10 (GMM) Pastor Maldonado has admitted there is "a chance" he will switch teams ahead of the 2013 season.
The Spanish GP winner said he could not comment because the great British team always waits until the end of the year to announce its lineup for the following season.
But now, with Chavez soundly in office until at least 2018, Maldonado has been quoted as admitting a change to another team is possible.
"At the moment there is a chance to go to other teams but we are considering remaining here (Williams), but it is still too early," the 27-year-old is quoted by Sky Sports.
"It is difficult to say, until other teams have confirmed their drivers you never know," he added.
The 2013 lineups at top teams Red Bull, McLaren and Mercedes have all been confirmed, but theoretical vacancies at Ferrari, Lotus, Sauber and Force India still exist.
