South Korea's opposition party urged the Constitutional Court to swiftly rule on the impeachment of suspended President Yoon Suk Yeol, calling further delays "irresponsible" and contributing to growing social unrest.

Yoon was impeached over his controversial declaration of martial law on 3 December, and the court held hearings last month to decide whether to formally remove him from office.

Although experts anticipated a ruling by mid-March, the court has yet to decide, making Yoon's case the longest deliberation in its history.

Over the weekend, protests erupted in Seoul, with roughly 100,000 people demanding Yoon's removal, alongside large demonstrations in support of him.

"The nation and its people have reached their limits," opposition MP Kim Min-seok said. "Any further delay would be abnormal and irresponsible."

Local authorities have imposed a drone ban around the court, speculating that the ruling may come soon. However, predictions on the verdict remain uncertain, with some expecting it later this week.

Police are preparing for potential unrest, including the closure of nearby businesses and the establishment of protest-free zones. Special units may also be deployed to address bomb threats.

In addition to impeachment, Yoon faces a criminal trial for declaring martial law, the first sitting South Korean president to be tried for insurrection. His supporters have rallied every weekend, with Yoon's release from detention boosting their momentum.

The Constitutional Court's decision is seen as pivotal, with experts suggesting it could spark violent clashes depending on the outcome.
