Panaji, Aug 27 (IANS): Delhi Chief Minister Arvind Kejriwal is known for engineering fake pre-poll surveys some of which are projecting the AAP winning the next assembly elections in Goa and Punjab, Congress leader Digvijay Singh said here on Saturday.

He also said Kejriwal fell out with Yogendra Yadav, a well known psephologist, because the latter refused to fabricate a poll survey -- and that the Aam Aadmi Party (AAP) leader is part of the RSS-BJP nexus out to eliminate the Congress party from Indian politics.

"No matter what Kejriwal says, he is known for getting fake surveys done, releasing and publicising them. That was one of the major reasons for the dispute between him and Yogendra Yadav, who is one of the most dependable and credible psephologists," Digvijay Singh told reporters here.

"Kejriwal wanted Yogendra Yadav to do a fake survey which he refused." 

Digvijay Singh said the AAP and the BJP are working together at the national level in line with the strategy of the Rashtriya Swayamsevak Sangh (RSS) for "Congress-mukt Bharat" (Congress-free India). 

He claimed that Kejriwal was present at a meeting of the Vivekanand International Foundation, an RSS-linked think tank, which strategised Narendra Modi's Lok Sabha election campaign.

"I challenge him to accept or deny the fact. Was he not a part of the discussion held in the Vivekanand International Foundation, which drew up the strategy of Modi's election as prime minister and was he not a part of the discussion along with the RSS?" Digvijay Singh said.

He also questioned Kejriwal's credentials as an Indian Revenue Service (IRS) officer, claiming the AAP leader remained on sabbaticals for most of the time he was in service.

"If you see his career in the IRS, he was never posted out of Delhi and most of the time he was on sabbatical. Every civil servant who is on sabbatical has to submit a report, which he never did. What was his record for checking tax evasion? He never comes out on that," Digvijay Singh said.
