Jaipur, June 30 (IANS): The Bharatiya Janata Party here on Tuesday maintained that the Dholpur Palace in the state belonged to Rajasthan Chief Minister Vasundhara Raje's son Dushyant Singh and challenged the Congress to prove it to the contrary.

Dushyant Singh is a Bharatiya Janata Party (BJP) MP from the state's Jhalawar-Baran constituency.

State BJP chief Ashok Parnami, in a press conference on Tuesday, showed some documents, including some court and family settlement papers, to the reporters to say that the palace actually belonged to Dushyant.

"The Congress is unnecessarily levelling baseless allegations and indulging in petty politics," he said. "We are giving replies based on documentary proof. Anyone is free to verify the documents...you can get the documents through RTI."

Parnami asked if the Congress found something wrong in the deal, why did it not initiate any probe when it was in power both at the Centre and the state.

Terming the charges levelled by senior Congress leader and former union minister Jairam Ramesh in a press conference earlier on Tuesday, as baseless and unsubstantiated, the BJP leader said the documents shown by him "prove that Dushyant holds the Dholpur Palace's ownership".

Rajendra Rathore, Rajasthan's parliamentary affairs and medical and health minister, at the press conference challenged Ramesh to join a debate with him and termed the Congress charges as absurd.

"Either he should prove the charges or else quit politics," Rathore said.
