Allies of embattled Jharkhand Chief Minister Shibu Soren have demanded that he quit immediately to clear the political uncertainty, following his failure to enter the state assembly.

"We all adhere to the Constitution. And Guruji (Soren) should have resigned immediately after his defeat in the Tamar bypoll. He should resign forthwith," Deputy Chief Minister Stephen Marandi said.

Soren, who met his party MLAs on Saturday, said the JMM had decided to intimate the central United Progressive Alliance leadership that their party leaders would not accept anything less than one of their own MLAs succeeding the present chief minister.

Senior Rashtriya Janata Dal Member of Legislative Aseembly and ex-minister Girinath Singh also said it would be better if Soren resigned without "wasting any more time".

Asked on the Jharkhand Mukti Morcha leader's bid to project one of his party's MLAs for the top seat, Singh said, "Unless Soren resigns, nothing could be discussed."

Congress MLA Sukhdev Bhagat said the Congress had first supported Independent MLA Madhu Koda and later Soren and there should be no more experiment.

"We have faxed a letter to the high command venting our feelings that there should a Congress-led government in the state or seek fresh elections under president's rule," Bhagat said.

State UPA chairman Koda has been more diplomatic in his remarks, saying he would adhere to the central UPA leadership's diktat.
