Japan's main governing Liberal Democratic Party has rejected an opposition demand to question former prime minister Abe Shinzo in the Diet over costs for annual parties.
Media outlets have reported that Abe's office allegedly shouldered part of the costs for parties at hotels in Tokyo held on the eve of Abe's annual cherry blossom viewing events.
Prosecutors in Hiroshima Prefecture, western Japan, are questioning a secretary of Upper House member Anri Kawai on Friday over a suspected violation of the election law.
The prosecutors suspect Kawai paid her campaign staff above the legal limit during her successful run for the Upper House in July last year. They raided her office on Wednesday.
