Japanese Prime Minister Kishida Fumio says he is considering disbanding a faction that he previously headed, amid a political fund scandal involving factions within his Liberal Democratic Party.

The Kishida faction is one of those suspected of having failed to declare some of the revenues from fundraising events in their political funds reports.

Tokyo prosecutors plan to bring a summary indictment to a former chief treasurer of the Kishida faction for allegedly failing to report about 30 million yen, or around 200,000 dollars, over three years through 2020.

A summary indictment means that prosecutors ask a summary court to impose a fine on the accused.

Speaking to reporters on Thursday evening, Kishida said he is considering the Kishida faction's disbandment. He said it could be an option if it will help regain public trust in politics.

Asked if he intends to urge other factions to disband, Kishida just said all he is considering now is what his party can do to regain people's trust.

Kishida had led the faction since 2012, but left the group last December as the money scandal involving LDP factions widened. He said he would try to restore people's trust in politics from a more neutral position.
