The Congress has decided to suspend former external affairs minister K Natwar Singh from the party's primary membership.

Natwar was indicted in the United Nations' corrupt oil-for-food scam.

The disciplinary committee of the Congress, which met under the leadership of former Kerala chief minister A K Antony in New Delhi, has also sent him a show cause notice asking him to explain why he shouldn't be expelled.

The party also asked him to explain why he moved a privilege motion in Rajya Sabha against Prime Minister Manmohan Singh.

Defence Minister Pranab Mukherjee, AICC Treasurer Motilal Vora and Power Minister Sushil Kumar Shinde also attended the meeting.
