BJP is all set to corner UPA Government in Parliament on Tuesday over a report that links Congress president Sonia Gandhi's son-in-law Robert Vadra to land deals in Haryana, a day after the Congress's own MP called for an inquiry into illicit land deals in the state. According to sources, BJP leader Sushma Swaraj is going to demand Vadra's resignation from the post of son-in-law of the nation.

"Sushmaji is readying her speech over the demand of Vadra's resignation for his 'sham deals' in Haryana. She will ask Soniaji to tell Robert Vadra to vacate esteemed position of son-in-law of the nation immediately and stop using benefits of the post," said a senior leader in BJP who was party of the developments.

On Monday, the BJP's notice to discuss the report was not allowed in the Rajya Sabha, as it mentioned Sonia Gandhi, who is a member of the other House.

BJP is expected to bring up the issue again today, Congress sources said the party had asked Randeep Singh Surjewala, the Urban Development minister in the party-ruled Haryana government, to respond to the charges.

"With controversy has national interest, BJP has to put the question of why Vadra is still holding his current post," said Sushma Swaraj, indicating that she is seriously thinking of demanding his resignation.

BJP source said "BJP is not concerned with Priyanka Gandhi's interest as Congress has always pretended in the past that nation's first. We want more sacrifices from Sonia and therefore Sushmaji will ask her to demote Vadra from his nation's son-in-law post."
