Seoul: South Korean President Park Geun-Hye has hired a lawyer ahead of questioning by prosecutors over a snowballing political scandal that has engulfed her administration, her spokesman said on Tuesday.
Park, who would be the first sitting president to be interrogated in a criminal case, has seen her approval ratings plunge, with hundreds of thousands of protesters taking to Seoul's streets on Saturday demanding she resign.
The scandal centres on Park's shadowy confidant Choi Soon-Sil, who is accused of using her ties with the president to coerce local firms to donate millions of dollars to non-profit foundations that Choi then used for personal gain.
Choi, 60, is also accused of interfering in state affairs to the extent of nominating officials and editing Park's speeches even though she has no official title or security clearance.
Prosecutors on Sunday announced a plan to formally quiz Park this week on Wednesday at the latest over allegations she helped Choi extract money from the companies and allowed presidential aides to leak documents to her.
Impossible' deadline
But Park's newly retained lawyer, Yoo Young-Ha, said it would be "impossible" for him to go over the necessary details of the case by Wednesday and called on prosecutors to push back the deadline.
"As her attorney, it would be helpful to uncover the truth if I can fully prepare for the case," Yoo told reporters.
He said Park was "heartbroken" over the current situation but added she was willing to "sincerely" cooperate with the probe.
Under South Korea's constitution, the incumbent president may not be charged with a criminal offence except insurrection or treason.
But many have argued the sitting president can be investigated by prosecutors and then charged after leaving office.
Choi, whose father was an elusive religious figure and a long-time mentor to Park until his death in 1994, was arrested earlier this month for abuse of power and fraud. Two presidential aides have also been arrested.
The probe widened again Tuesday, when prosecutors raided the office of Samsung's advertising unit, Cheil Worldwide, as part of an investigation into Choi's relatives, the Yonhap news agency said.
Samsung made the largest donation of some 20 billion won ($17.5 million) to Choi's foundations and is accused of separately offering 2.8 million euros ($3.1 million) to Choi to bankroll her daughter's equestrian training in Germany.
Prosecutors found evidence that Cheil had made questionable donations to a non-profit sports foundation controlled by Choi's niece, Jang Si-Ho, Yonhap said.
Jang, described by local media as a key Choi aide, is accused of using the foundation and a sports management firm controlled by her to funnel state funds and to extract donations from local firms.
The Tuesday raid came after prosecutors quizzed the Samsung group scion Lee Jae-Yong and the heads of other powerful conglomerates including Hyundai over the scandal.
The "donations" from the conglomerates to the two foundations controlled by Choi amount to about 77 billion won.
Shin Dong-Bin, chairman of Lotte Group, was also summoned to the prosecutors' office on Tuesday to answer questions.
