South Korea's beleaguered ex-president Yoon Suk Yeol will on Friday receive the first verdict on charges linked to his botched martial law attempt in 2024.

He is facing eight separate trials for charges ranging from abuse of power and insurrection to violating campaign law.

This comes more than a year after his short-lived decree threw South Korea into political turmoil, leaving it deeply divided.

Here's what to know about the key charges laid against Yoon.

Under South Korea's constitution, sitting presidents are immune from criminal persecution, except for on charges of insurrection and treason.
