My dear friend , Proportional representation is that system in which noone get majority.But the party having highest no of seat can get the oppertunuty to lead the country.  It happend in the world.

In nepal maoist got majority in direct election and becomes the biggest party in proportional representation.The differnece is very high. maoist -220 vs 110(second).  Thus maoist should lead the government.

Other parties should learn to respect the mandate of the people.
