SEOUL: South Korean President Park Geun-hye's approval rating remained at an all-time low for a second week amid a deepening political crisis, according to a Gallup Korea poll released on Friday, underscoring the challenges faced by her administration. Park's presidency has been rocked by allegations that a personal friend of hers used her ties to meddle in state affairs and wield improper influence. Gallup said its survey of 1,003 South Koreans from Nov. 8-10 showed that 90 percent of participants disapproved of her performance, up from 89 percent last week and a new high. The results of the Gallup poll came after Park gave her second public apology last week and indicated she was willing to relinquish some power.
