Bhopal: Senior Congress leader Digvijay Singh has rubbished the exit polls, being aired on some news channels, predicting an edge for BJP over Congress in recently-concluded Assembly elections in five states.

"There is no meaning in such exit poll results and they deserve to be consigned to dustbin," the Congress general secretary told reporters last night at the Raja Bhoj airport.

Digvijay's son Jaiwardhan, accompanying his father, said exit polls are unreliable and are error-prone.

Responding to a query on the alleged PMT scam under the watch of state Professional Examination Board, Digvijay alleged ruling BJP government was shielding all the accused.

According to investigators, private racketeers in cahoots with some officials of the MPPEB allegedly secured admission for students in medical colleges in the state through Pre-Medical Test (PMT).

"If Congress comes to power, it will ask for a CBI probe into the matter," Digvijay said.

On arrest of a BJP Youth Wing leader in connection with murder former RSS pracharak Sunil Joshi, he said, "My stand on involvement of RSS in the murder is vindicated now".
