Bipartisanship & Cohabitation

Japan's Prime minister resigned. He had once proposed to his counterpart - leader of the main opposition party to cohabit in the same cabinet. His counterpart declined as a matter of course.

I can't assert whether his attempt was good though in general bipartisanship is effective in some areas as defence, humanitarian issues, but it's not always necessary in various other issues that relate to our ordinary daily life.
