Kolkata, March 8 (IANS): Accusing both Congress and BJP of pursuing "pro-rich policies", Communist Party of India-Marxist leader Buddhadeb Bhattacharjee Saturday asserted only the Left parties had the right alternative policies.

"There is no difference between policies of Congress and BJP, their sole aim is making richer the rich and robbing the poor.

"They can dole out subsidies to big corporates but when comes to giving subsidies for public distribution system, they don't have the money," said Bhattacharjee, a former West Bengal chief minister, while addressing a rally in Ranaghat in Nadia district.

Attacking the centre over its policies especially fuel pricing and rising prices of commodities, Bhattacharjee urged people to drive away the Congress-led United Progressive Alliance (UPA) and prevent the BJP-led National Democratic Alliance (NDA) from coming to power.

"This government has been pursuing anti-people policies continuously, so the time has come to drive them away and at the same time prevent the BJP from coming to power.

"The people of the country want allround welfare and only the Left parties have the alternative policies for the welfare of the common man including STs, SCs, backward classes and minorities," added Bhattacharjee.
