The ruling Liberal Democratic Party is considering fielding pop singer Eriko Imai, formerly of the megahit dance group Speed, as an official candidate in the Upper House election this summer, a report said Friday.

In response to the report, LDP Secretary-General Sadakazu Tanigaki was noncommittal. During a regular press briefing Friday morning, Tanigaki said he was "not aware" of the move at all.

"To be honest, I didn't even know what Speed was. People around me called me a dinosaur for that," Tanigaki, 70, said of the now defunct female band that was the zeitgeist of 1990s Japan.
