Philippines group seeks Marcos Jr poll ban

A group opposing the candidacy of the son of late Philippines dictator Ferdinand Marcos for next year's presidential race will ask the election commission to bar him from running because he has been convicted for tax evasion.

Called the Campaign Against the Return of the Marcoses and Martial Law, the group will file a petition on Wednesday for the disqualification of Ferdinand Marcos Jr after he emerged as the frontrunner for May's election.

Former congressman Satur Ocampo, one of the group's convenors, said the petition, like one filed by another group, is grounded on Marcos' more than two-decade old conviction for tax evasion.

"Public officials who violate the internal revenue code are perpetually disqualified from holding any public office and participating in election," Ocampo, who fought the Marcos dictatorship, told Reuters, citing an article of the code.

The late dictator ruled the Philippines for almost two decades until he was overthrown in 1986 in the 'people power' revolution. He died in exile in 1989.

His wife and children have repeatedly denied allegations billions of dollars of state wealth were plundered while Marcos was in power, estimated in 1987 to be worth $A14 billion.

A trial court convicted Marcos Jr of tax evasion in 1995 for failing to file his income tax returns from 1982 to 1985. The conviction was upheld by an appeals court in 1997.

However, Marcos Jr has been elected as a governor, congressman, and in 2010, as a senator.

The poll body has scheduled a preliminary conference for November 26 on the earlier disqualification complaint filed by a group representing political detainees, human rights and medical organisations against Marcos.

Marcos, 64, has said the petition "is without merit and has no legal basis".

He announced on Tuesday that the daughter of current president Rodrigo Duterte has agreed to be his vice presidential running mate, confirming weeks of speculation of an alliance between two powerful families.
