New Delhi: A churning is on in Punjab Congress after the party's shock defeat in the state assembly elections with PCC chief Capt Amarinder Singh coming under sharp attack from within for the poll debacle.

With the party still analysing the reasons for its defeat, demands are growing for a change in the state leadership and a revamp to prepare itself for the 2014 Lok Sabha polls to take on the Akali-BJP combine.

This has led to an open slug-fest between Amarinder's supporters and his detractors. While party leaders are openly airing their differences in public despite a gag-order by the high command, workers are feeling disillusioned.

In view of the successive defeat in the state, Congress general secretary and in-charge of Punjab affairs Gulchain Singh Charak has in his report also stressed on the need for a revamp.

"There is a need for a revamp...but there is no rebellion in the party in Punjab. All leaders will talk on the party platform," Charak told.

While a number of senior leaders have already individually met the three-member Committee headed by Defence Minister A K Antony and given their opinion on the party's defeat, many other state leaders opposed to Amarinder Singh are seeking time to appear before the panel to air their grievances.

With the Antony panel likely to submit its report to AICC chief by the end of April, many Punjab leaders are getting uneasy and are keen on meeting the panel before that happens.

While Delhi Chief Minister Sheila Dikshit is busy in the civic polls, Shinde is abroad for a few days and Parliament session is starting from April 24.

Party president Sonia Gandhi had formed the Antony Committee, which has Dikshit and Power Minister Sushil Kumar Shinde as its other members, to analyse the reasons of Congress' poor performance in the state assembly polls.
