A Congress delegation, including party chief Sonia Gandhi, on Thursday urged President Ram Nath Kovind to call for Union home minister Amit Shah's resignation over his alleged 'abdication of duty' during the communal violence in Delhi and remind the Centre of its 'raj dharma'.

The delegation, including former Prime Minister Manmohan Singh, Leader of Opposition in Rajya Sabha Ghulam Nabi Azad, and party leaders Ahmed Patel, P. Chidambaram, K. C. Venugopal, Priyanka Gandhi Vadra, Anand Sharma and Randeep Surjewala, also submitted a memorandum to the President over the wave of violence in Delhi.

Reading out parts of the memorandum before the media outside the Rashtrapati Bhavan, Sonia Gandhi said that instead of taking remedies to diffuse the situation in Delhi, the Centre and the newly-elected Delhi government have remained 'mute spectators' to the violence.

The violence has taken the lives of 34 people and businesses have fallen prey to looting, Gandhi said.

The party also asked the President to call for the resignation of the Home Minister over alleged 'abdication of duty' during the violence.

Manmohan Singh, in his remarks to the media, said the Congress leaders called upon the President to convey to him that what has happened in the last four days in the national capital is a matter of deep concern and national shame.

He alleged that there had been a 'total failure' on the part of the central government to control the situation.

The Congress requested the President to remind the central government of its 'raj dharma', Singh said.
