Varanasi, March 28 (IANS): Finance Minister Arun Jaitley on Saturday said the AAP government must not lose opportunity to work for the people of Delhi due to "political immaturity".

"People voted for this government with high hopes and they expect the promises to be fulfilled. Because of political immaturity, they should not lose this opportunity," Jaitley said in response to a question on Saturday.

He also slammed the recording of Delhi Chief Minister Arvind Kejriwal's conversation by a party member, calling it a new kind of politics.

"This is a new kid of politics that conversation between two politicians is recorded, this is not expected," he said.

Differences in the Aam Aadmi Party (AAP) came out in open on Friday when Yogendra Yadav and Prashant Bhushan addressed a press conference, and offered to resign from the party.

In another press conference, AAP members slammed the two for working against the interests of the party.

Later, a tape surfaced in which Kejriwal is heard slamming Yadav and Bhushan and threatens to walk out of the party to form a new outfit.

The conversation was allegedly between Kejriwal and Umesh Singh, an AAP worker from Benaras. The authenticity of the tape has not been established.
