It is not only politicians who have been outraged by Yoon’s actions.

Yang Soonsil, 50, is a seafood shop owner at Namdaemun market in the South Korean capital, Seoul. She told the BBC that she had felt fear and disbelief when martial law was declared.

“I have lost complete trust in him [Yoon] as a president, I don’t think he’s my president any more,” she said.

“We need to fight until the end, we can’t let him maintain his position as a president.”

At the same market was shopper Han Jungmo, who said that Yoon’s apology was not enough.

“He must either step down voluntarily or be impeached, if he’s not willing to,” he said, adding that the president had broken trust with the people.

“If he continues to insist on being president, then it would be a very hopeless situation because I believe for this president, this martial law is not the only misdeed he has conducted.”

South Korea was plunged into political turmoil late on Tuesday night when Yoon made the shock martial law declaration.

He cited threats from “anti-state forces” and North Korea. However, it soon became clear that his move had been spurred not by external threats but by his own domestic political troubles.

Some lawmakers jumped over barricades and fences to get past security forces in order to convene in parliament and void Yoon’s decree.

Yoon rolled back the declaration six hours later after MPs voted it down but there had been concern he would attempt to make a second decree. Some lawmakers had been staying near the National Assembly to make sure they were there ready to void it.

Before his attempt to place the country under military rule, Yoon had been beset by low popularity ratings, corruption allegations and an opposition-led legislature that reduced him to a lame-duck leader.
