Hyderabad, Jul 9 (IANS): Cracking the whip, the ruling Congress party in Andhra Pradesh Friday served showcause notice to a leader loyal to party MP Y.S. Jaganmohan Reddy.

The disciplinary committee of the party served the notice on general secretary Ambati Rambabu for making certain remarks against Chief Minister K. Rosaiah.

Rambabu was issued notice even as Jagan continued his 'Odarpu yatra' in Srikakulam district in defiance of party's central leadership.

The former chief minister Y.S. Rajasekhara Reddy's son is visiting the families of those who died of shock or committed suicide following the death of his father in a helicopter crash Sep 2 last year.

For the second day the central leadership took no action against Jagan though it had warned him not to violate discipline by resuming the yatra.

Rambabu told reporters that he would send a reply to the notice. "I have not breached the discipline. Since this is an internal matter of the party, I will send a reply," he said.

The party general secretary had hit out at Rosaiah Wednesday after the latter asked party legislators to stay away from Jagan's yatra.

He had remarked that Rosaiah should be indebted to YSR's family for becoming the chief minister. He also stated that Rosaiah became the chief minister by accident due to the sudden death of YSR.
