New Delhi: Congress president Sonia Gandhi’s son-in-law Robert Vadra on Wednesday lashed out at union minister Giriraj Singh after he made racist remarks about her “white skin”.

“Appalled to read the comments by a union minister on the Congress president, my mother-in-law,” said a post on Vadra’s Facebook page.

Describing her as a woman of “immense dignity”, Vadra said: “Is this the way we speak about a lady who has undergone hardships all (through) her life and has lost her loved ones for the nation?

“If the government and their ministers cannot respect her, if they make sexist, racist comments about her, what about all the other women in our country?”

At an event in Bihar on Tuesday, Singh said: “If Rajiv Gandhi had married a Nigerian and if she wasn’t white skin, would Congress accept her (Sonia Gandhi) as a leader?”
