SEOUL — South Korean President Park Geun-Hye today agreed to submit to questioning by prosecutors investigating a corruption scandal engulfing her administration, accepting that the damaging fallout was "all my fault".

In a televised address to the nation, Park denied some of the more lurid rumours surrounding the scandal -- including reports that she had fallen into a religious cult and conducted shamanist rituals in the presidential Blue House.

It was the second time in 10 days that Park has felt compelled to speak directly to the country about the crisis that erupted last month over a close personal friend accused of embezzlement and meddling in key state affairs.

On Thursday, a Seoul court formally approved an arrest warrant for Choi Soon-Sil, Park’s long-time confidante, on charges of fraud and abuse of power.

"If necessary, I am willing to sincerely respond to prosecutors’ investigations," Park said, in an at times emotional address.

"These latest developments are all my fault and were caused by my carelessness," she said, adding that she had "allowed my guard to drop" around Choi.

"I can’t forgive myself ... and it is hard to sleep at night."

The scandal has shattered public trust in Park’s presidency, which has more than a year left to run, triggering large street protests, calls for her resignation and a major reshuffle of her senior ministers and top advisers.

A new Gallup poll released yesterday showed Park’s approval rating down at five per cent. Choi, 60, is accused of leveraging her close relationship with Park to coerce local firms into donating large sums to dubious non-profit foundations that she then used for personal gain.

Choi also faces allegations that she interfered with government affairs, including the nomination of senior officials.

Making Park a part of the investigation treads on sensitive ground, as South Korea’s constitution does not allow for a sitting president to be charged with a criminal offence, apart from insurrection or treason.

But senior government officials have suggested Park could be quizzed by prosecutors as part of a general probe.

"There have been claims that I fell for a religious cult or had (shamanist rituals) performed in the Blue House, but I would like to clarify that those are absolutely not true," Park said in her address today.

Opposition parties, while vocal in their criticism of Park’s behaviour, have stopped short of calling for her resignation which would necessitate an early presidential election that they would not be confident of winning. — AFP
