Peru's congress suspended lawmaker Kenji Fujimori late Wednesday over corruption allegations but lacked a quorum to dismiss him as part of a fight with his sister for control of their father's political dynasty.

After 11 hours of debate in a special plenary session, 61 lawmakers voted to suspend the youngest son of former president Alberto Fujimori.

But many lawmakers then walked out and the speaker of the chamber, Luis Galarreta, suspended the session citing a lack of quorum -- 67 lawmakers -- before it could vote on a motion to dismiss Fujimori altogether as sought by the party of his sister and rival, Keiko Fujimori.

"I say this to my sister: 'here, you have my head,'" Kenji Fujimori said after the vote. "We are victims of a parliamentary dictatorship."

Fujimori, 38, is accused of attempting to buy votes to keep disgraced former president Pedro Pablo Kuczynski from being impeached. Kuczynski ended up resigning, in March.

With Fujimori now out of congress and under investigation, the vote Wednesday night shapes up as a win, albeit a costly one, for his sister in their battle for control of their father Alberto's political legacy.

But the younger Mr. Fujimori is not disqualified from politics altogether and he and his sister could even square off against each other in presidential voting in 2021.

After the vote to suspend him, half of the lawmakers in the chamber walked out, leaving only supporters of his sister. That meant there was no quorum to vote on sacking Fujimori altogether.

"If anyone believes that my political life ends here, they are totally wrong, because this is just a beginning," Fujimori said before the vote, shedding a few tears.

   Breaking ranks

Many see Kenji, who polled more votes than any other candidate in Peru's last two legislative elections, as likely to run against his sister for the presidency in 2021.

The drive to ban Fujimori from politics was in fact aimed at keeping him out of that presidential race, analyst Fernando Tuesta told AFP.

Corruption-tainted Kuczynski survived an impeachment vote in Congress last December thanks to the abstentions of Kenji Fujimori and his supporters, who broke ranks with his sister's Fuerza Popular (Popular Force) party.
