The authorities in South Korea were expecting tens of thousands of protesters to descend on central Seoul on Friday as the nation’s Constitutional Court decides the fate of President Yoon Suk Yeol.

       At least 14,000 police had been deployed to the area around the court, closing subway stations and locking down an area near a former royal palace that is popular with tourists and home to major businesses. Drones have been banned from the area, and schools, vendors and businesses have been ordered to close.

       The first protests were set to start at 10 a.m. local time, ahead of a possible decision by the court that could come as early as 11 a.m. Mr. Yoon was not expected to attend the reading of the decision, which will determine whether he will be formally removed from office or returned to power.
