The parties which want to implement the reservation should set an example by having 49.5% of the total candidates from reserved category . The party posts should also be reserved in the same proportion . Further since this amounts to almost 50 % reservation every seat of the member of the parliament should be a reserved seat in one election and a non reserved seat the next election . To be precise if Mr arjun Singh fights a election under non reserved seat from his constituence the next time that constituency should be reserved . This should go on by rotation .
