The senior leader also said that the BJP should establish facts if it has anything on alleged link between party President's son-in-law and fugitive arms dealer Sanjay Bhandari.
Vadra has found himself at the centre of a fresh maelstrom after a national news channel's expose alleging his link to Bhandari.
Dikshit said Vadra, and not Congress should come forward to explain the alleged link with the arms dealer.
"Why Rahul Gandhi has remained silence. No tweets on the flats getting refurbished, no tweet on his brother-in-law getting money. Is the Congress leadership by remaining silence suggesting that yes they looked it but took it the other way? Can somebody from Congress cannot come and give this platitude but tell us how this happened," the minister had said.(ANI)
