Ruling and opposition parties on Tuesday harshly criticized minor parties Reiwa Shinsengumi and the NHK Party over their handling of Diet seats.
On Monday, Reiwa announced its plan for the five years remaining in the six-year term of a party member who was elected to the House of Councillors in the proportional representation section of last July's election but later resigned. The party said the seat would be filled in what it calls a rotation system, with its five members who lost in the proportional representation section filling the seat by turns.
Under the Public Offices Election Law, if a member of the upper house elected in the proportional representation section resigns, the runner-up on the same party's proportional list is to take the post vacated. The rotation system eyed by Reiwa is said by some to fall within the bounds of the law.
