The main opposition Democratic Party's new leader Renho may appoint former Prime Minister Yoshihiko Noda as the party's secretary-general, sources close to the matter said Friday.

Renho, who became the first woman to head the party following Thursday's leadership election, is also thinking about picking Goshi Hosono, a former environment minister, as deputy leader of the party, the sources said.

She is expected to seek approval of her choices at a meeting of Diet lawmakers to be held at party headquarters Friday afternoon, they said.
