The roster is finally set for next month’s Seoul mayoral by-election with the pan-opposition choosing Oh Se-hoon as its candidate against Park Young-sun of the progressive block.

Former Seoul Mayor Oh of the main opposition People Power Party defeated former presidential candidate Ahn Cheol-soo of the People’s Party in an opinion poll the two sides jointly commissioned to field a single candidate.

In a much-criticized decision some ten years ago, Oh resigned from the position of Seoul mayor after his controversial campaign failed to end the then-liberal opposition’s push for free lunches for all 810-thousand elementary and middle school students.

Oh’s now facing another formidable heavyweight in former SME minister and four-term lawmaker Park of the ruling Democratic Party.

The winner of the Seoul election will serve for the 14 months left in late Mayor Park Won-soon's four-year term.
