They may be on the same side of political power, but that did not stop Railway Minister Mamata Banerjee and her predecessor Lalu Prasad from taking pot-shots at each other during the presentation of Railway Budget in the Lok Sabha on Friday.

Banerjee, who presented her first Budget in the UPA's second tenure, was interrupted in her speech, interestingly not by anyone from the opposition benches but from the leader of RJD which is an ally of the Congress-led coalition.

During Banerjee's hour-long speech, the Railway Minister and Prasad were seen taking digs at each other.

"I respect you... You have done some things and I will do some things...I need support," she told the RJD chief as he kept making certain comments on her budget proposals.

While announcing a scheme providing employment to the tribals near Lalgarh, the Trinamool Congress chief addressed Prasad and said, "Let me do one or two (for Bengal). You did so much (for Bihar)."

At this, Prasad got up and told her, "I am not interrupting you. Why are you after me?"
