The House of Representatives Foreign Affairs Committee will again try to get former diplomat Kazuhiko Togo to give testimony in connection with a scandal involving a government-funded committee on Russia, panel members said Thursday.

The members said the Lower House committee will deliver the letter of request to Togo's Tokyo residence. He is currently staying in Europe.

The panel initially asked Togo to give unsworn testimony in early April, when he was dismissed from the ministry for improper conduct stemming from his close ties with arrested lawmaker Muneo Suzuki.
