Âé¶¹´«Ã½ ruling coalition collapsed on Friday after its junior partner Komeito quit, raising doubts about whether conservative Sanae Takaichi will become the country¡¯s first female prime minister.

The announcement came less than a week after Takaichi became the Liberal Democratic Party¡¯s fifth leader in as many years, tasked with winning back disaffected voters.

The main reason given by Komeito party chief Tetsuo Saito was what he called the LDP¡¯s failure to tighten rules on the funding of political parties.
