Seoul Mayor Oh Se-hoon will declare his intention to run for president this weekend.

Oh’s aides announced in a press release Wednesday that the mayor will make the declaration Sunday. 

While Oh has not yet disclosed where he plans to make the announcement, the aides said he will pick a symbolic spot where he has pursued policies to assist vulnerable members of society.

Oh’s key aides, including Vice Mayor for Political Affairs Kim Byung-min, tendered their resignations to assist Oh in his pursuit of the top office. 

Shortly after his resignation, Kim will serve as the spokesperson for Oh’s campaign.
