Robert Vadra on Wednesday moved the Delhi High Court seeking quashing of an FIR registered by the Enforcement Directorate (ED) in a money laundering case in which he has been questioned by the probe agency.

Vadra, the brother-in-law of Congress President Rahul Gandhi, has also sought to declare various provisions of the Prevention of Money Laundering Act, 2002 as ultra vires to the Constitution.

A Delhi court had on Tuesday extended Vadra's interim protection from arrest till March 25 in the case.

The ED case relates to allegations of money laundering in the purchase of a London-based property at 12, Bryanston Square, worth 1.9 million pounds.

The property is allegedly owned by Vadra.
