Camarines Sur Rep. Leni Robredo on Tuesday denied allegations of cheating and a supposed plan of the administration party to impeach presumptive President Davao City Mayor Rodrigo Duterte.

Speaking to reporters in Quezon City, the Liberal Party (LP) vice- presidential candidate insisted that there is no so-called "Plan B" to impeach Duterte supposedly to pave the way for a turnover of power to her if she wins the race.

"Wala po itong katotohanan," said Robredo, adding that no less than LP standard-bearer Mar Roxas has already conceded to Duterte and even wished him success.

She said she is ready to give Duterte her full support for the good of the Philippines, and will also accept any assignment that may be given to her.

Robredo is in a close fight with Senator Bongbong Marcos, only separated by around 200,000 votes, according to the latest partial and unofficial results of Monday's elections.

She denied allegations of "dagdag-bawas," as claimed by Marcos, who initially had a lead of close to 1 million but was now trailing Robredo.

"Kung meron man, ako po mismo yung mauunang magkontra sa kahit anumang klase ng pandaraya," she said. "Pero ngayon po, wala akong ma-imagine kung papaanong klaseng pandaraya at papaano ito gagawin."

She added that it is unfair to throw such as accusation. She noted that she never accused Marcos of cheating all the times he led in pre-election surveys.

"Kasi I think napaka-unfair na accusation na sinasabing nandadaya nang hindi mo naman sinu-substantiate. Kasi ang dali lang sabihin eh, ang dali lang sabihin na nandadaya," Robredo said.
