The ruling Liberal Democratic Party will decide whether party heavyweight Muneo Suzuki should testify as a sworn witness in the Diet after the Foreign Ministry submits a report on its probe into his suspected involvement in various scandals, LDP Secretary General Taku Yamasaki said Sunday.
"We will wait for the Foreign Ministry's investigation report and may discuss whether (the Diet) should exercise the right to conduct an investigation," Yamasaki said on an NHK TV show.
Confusion will result unless lawmakers deal with the issue based on the facts, he said.
