Fujimori has been in self-imposed exile in Japan since 2000

Mr Fujimori told a BBC online forum a third of Peruvians wanted him to run for president again, and that the ban against him was politically motivated.

Mr Fujimori sought refuge in Japan four years ago after a corruption scandal.

He is wanted in Peru on a range of charges, including murder and kidnapping. He denies any wrongdoing.

'Return'

In a written reply to questions from readers of BBC news website BBCMundo.com, Mr Fujimori said "the opportunity to return to Peru will come".

"I have decided to come back to Peru and run in the next general elections in 2006," he wrote.

He declined to reveal how he planned to override the ban on public office.

The country's prosecutors are seeking a 30-year jail sentence for its former leader, who also faces allegations of corruption stemming from his 1990-2000 rule.

Peru is working to have him sent back, but he is a citizen of Japan, which bars the extradition of its citizens.

Mr Fujimori claimed Japanese citizenship based on the fact that his parents were born there.

In April, the Peruvian electoral authority invalidated a new political party set up by the former president.
