Facing fresh allegation of flouting rules in awarding contract to build a dam besides the Rs 206 'purchase' scam, Maharashtra Minister Pankaja Munde rubbished the charges as mere 'scam of words' and said she will step down if found guilty of any charge.

Munde, who was away in London last week when the opposition Congress accused her of brazen violation of norms in awarding contracts for purchase of 'chiki' and a host of other items for anganwadis, said there was a 'politically motivated' move by the opposition to target her when she was not 'physically available to defend herself.'
