President Park Geun-hye has nominated the ruling Saenuri Party's floor leader Rep.
Lee Wan-koo as new prime minister as part of her Cabinet shake-up, Cheong Wa Dae said Friday.
Lee will replace Chung Hong-won as soon as parliamentary approval is granted.
"President Park Geun-hye accepted Chung's resignation as he offered to resign several times and nominated Rep.
Lee as new prime minister," said Yoon Doo-hyun, senior presidential secretary for press.
Earlier this week, Park said she would carry out a "small-scale" Cabinet reshuffle and partially reorganise the presidential office as she seeks to regain public confidence to push ahead with her economic reform drive.
According to a local pollster, her job rating plunged to 35 per cent last week, the lowest level since she entered office in early 2013.
