The Congress is likely to bring back several ministers if these four ministers quit their portfolio.

This comes after the Congress formed a panel headed by Defence Minister AK Antony to go into the causes of the party's defeat in the Punjab and Goa polls and its lackadaisical performance in Uttarakhand where it failed to get a majority on its own.

The review committee, which includes Delhi Chief Minister Shiela Dikshit and Union Minister Sushilkumar Shinde as members, gave its report to party president Sonia Gandhi.
