By Hyunsu Yim, Eduardo Baptista and Minwoo Park SEOUL (Reuters) -Supporters of impeached South Korean President Yoon Suk Yeol are adopting "Stop the Steal" slogans popularised by U.S. President-elect Donald Trump supporters and said they hoped the incoming president would help their embattled leader.

South Korea's political leadership was in uncharted territory Saturday after the sitting president resisted arrest over a failed martial law decree days before the warrant expires.The South Korean president was impeached and suspended last month after the bungled martial law declaration -- a political move swiftly overturned by parliament -- with a separate warrant later issued for his arrest.
