Kirit Somaiya, who has been in the forefront of BJP's attack on Congress over the AgustaWestland issue, has accused Congress chief Sonia Gandhi's son-in-law of benami transactions and floating many companies to park "non-transparent" money.
"I will raise the issue in Lok Sabha," he said.
In a related move, he has also written to the ED Director regarding "solar land scam" companies linked to Vadra.
The Mumbai North-East MP is also the Chairman of Energy Committee of Parliament.
Last week, Somaiya had attacked the Congress leadership in Parliament over the VVIP chopper scam. He had also written to the ED, asking it to "check" Congress vice president Rahul Gandhi's link with those involved in this as well as the CWG scam.
