With mayoral by-election of the two biggest cities coming up next month in South Korea about a quarter of the nation will be electing their new mayors.
Seoul's ballot is yet to come, but candidates from each major party have been confirmed.
The ruling Democratic Party's Park Young-sun is looking to merge with Kim Jin-ai, the candidate from Open Democratic Party.
Unifying the candidacies of two rivals from the opposition bloc will be a key factor in how the election will unfold.
A former Seoul mayor himself, Oh Se-hun won the primary for the main opposition People Power Party and another major candidate is Ahn Chul-soo, a former Presidential Candidate of the People's Party.
Oh and Ahn met on Sunday night to discuss forming a single opposition candidacy and will later decide who will run before registration opens on March 18th.
Another by-election coming up is for the mayor of Busan.
From ruling Democratic Party, Kim Young-choon, ex-Minister for Oceans and Fisheries, won the primary while Park Hyung-jun, a former chief presidential secretary for political affairs under former President Lee Myung-bak, is the candidate for People Power Party.
The city has historically been conservative but former mayor, Oh Keo-don took the job in 2018 for the first time as a liberal contender since nationwide local elections started in 1995.
However, the vacancy comes following his resignation after admitting to sexual harassment of his female aide last April.
"Seoul's vacancy is also linked to a sexual harassment case as former mayor, Park Won-soon, who also came from the ruling side, died in an apparent suicide last year following accusations from a female former aide.
Both by-elections will be held on April 7th, and the winners will serve the remaining term for the previous mayors which have just over a year to run.
