People of Delhi won't forgive Congress if it withdraws support to the Arvind Kejriwal-led government, Aam Aadmi Party (AAP) leader Prashant Bhushan said here today.

He said Lok Sabha elections are the next target for his party after the "success" in Delhi assembly polls.

"We are not in an alliance with Congress. Congress gave support because of its own compulsions. We said we won't accept any conditions," Bhushan told reporters here.

To a query what would AAP do if Congress withdraws support, Bhushan said "the people of Delhi won't forgive Congress in next polls if it pulls down the people's government."

"You are aware that we did not start out for electoral politics nor for grabbing power. Our aim was Jan Lokpal and corruption-free India. But the big parties taunted us that we won't be able to defeat them in polls," the senior Supreme Court advocate said.

"We also felt that people want a change. We elected them (politicians) for five years and they take graft from big companies and make laws which are not in people's interest," he said.

AAP's mission is to bring about a transformation in the country to ensure democratic and legal rights to the common man, he said.

The present power structures in the country, including the judicial system, do not guarantee meaningful participation of and rights to the vast majority of people, Bhushan said.

It was time that radical changes were brought about in every sphere of the polity including bureaucracy, police and judiciary, he said.

"We formed the party out of compulsion," he said.

The results of Delhi polls had damaged the ego of big political parties, he said while describing BJP as "overtly communal" and Congress as "covertly communal."
