We need two party system in India. Congress and BJP,both these parties are good. BJP has proved their caipability to rule our country and best opposition to congress. These small regional parties and Marxiest parties are always trying to destabilise the central government. we have lots of regional parties like DMK, AIDMK, PDP,PMK---- etc hundred of local parties in south indian states. Actually, all these small parties are threat for our national integrity.
