Prime Minister Shinzo Abe continued to face the backlash from his cronyism scandals on Monday as opposition parties made more vocal demands at a special Diet session for key individuals — including first lady Akie Abe — to give sworn testimony in the Diet.

After Monday's Upper House session, representative committee members from the ruling and opposition parties met to discuss whether to summon some of the key figures reportedly involved in the shady land deal to school operator Moritomo Gakuen.

But the ruling coalition only said it could not make a decision until its senior executives meet Tuesday morning, stalling the day's talks, according to Democratic Party lawmaker Takanori Kawai.
