Congress leader Randeep Surjewala said the matter should be probed by a sitting Judge of the Supreme Court.
The Congress today demanded sacking of Chhattisgarh Chief Minister Raman Singh and pressed for probe by a Supreme Court judge after audio tapes emerged suggesting financial inducements behind the party's candidate withdrawing from an assembly by-elections in the state last year.
"The tapes now prima facie prove the allegation. Keeping in view his tall promises of not allowing corruption at any cost, Prime Minister Narendra Modi should immediately sack, dismiss or force Chhattisgarh Chief Minister Raman Singh to resign. The matter should be probed by a sitting Judge of the Supreme Court," said All India Congress Committee (AICC) Communication Department Chief Randeep Surjewala.
The purported conversations between key political players of that time, reportedly recorded on tapes, also hints at the role of former Congress Chief Minister Ajit Jogi and his son Amit Jogi.
Chhattisgarh Congress issued a show cause notice to Amit Jogi and decided to wait for a report from the state unit to decide on the action against Ajit Jogi "since he is a member of Congress Working Committee."
"Examine the role of all by including that of Ajit Jogi or any other Congress leader's conduct. Since the Chief Minister holds a top Constitutional post in the state, he should immediately be asked to ensure a fair probe," said Mr Surjewala.
"Congress also assures that it will take appropriate action against its leaders after the probe finds anything against them. Congress stands committed to take action on the basis of the outcome of the probe," he added.
Recalling that the party in a petition to Election Commission had alleged inducement behind Congress candidate Manturam Pawar withdrawing from Antagarh bypolls in September last year, AICC general secretary BK Hariprasad said the tapes clearly prove that the party's allegations were correct.
"As far as Ajit Jogi is concerned, he is a Congress Working Committee member and only Congress President can take action against him... After going through the report of the state unit into this matter, the AICC Disciplinary Committee headed by A K Antony will take a call on action about Ajit Jogi," said Mr Hariprasad.
