02 July 2012, 52 members of Japan’s Diet (parliament) have resigned over the sales tax increases called for by Prime Minister Yoshihiko Noda.

The prime minister and the lawmakers who quit are part of the same political party, the Democratic Party of Japan (DPJ).  One of the lawmakers to resign is Ichiro Ozawa, who helped found the DPJ. He’s forming a new political party to challenge the government.

The members who left occupied positions in both houses of the Diet.  If the DPJ were to lose 55 members in the more powerful Lower House, then the DPJ would not be able to stop any recall of the prime minister.  The Lower House of the Diet appoints the Japanese prime minister, he is not elected by the general public.

Yoshihiko Noda is the sixth prime minister in the past six years.
