The opposition party also demanded that the Narendra Modi government tell the truth about Sushma Swaraj's relations with former Indian Premier League chief Lalit Modi.
"Sushma Swaraj must tell the people of the country how many times she has met Lalit Modi or if any of her family members had been in touch with the fugitive," Congress spokesperson Randeep Surjewala said at a media briefing here.
Surjewala demanded that the BJP government make public all letters exchanged between the previous UPA government and authorities in Britain over the Lalit Modi issue.
"We demand that the letters written by the then finance minister P. Chidambaram to the UK authorities on Lalit Modi in 2013 be made public," Surjewala said.
Congress demanded the resignations of Swaraj and Raje
All records are with the Indian government and it should make these public, he added.
Taking a dig at the Narendra Modi government, the Congress leader said: "From Maulana Masood Azhar to Lalit Modi, from Kandahar to London, the NDA government has been helping such people on humanitarian grounds."
Surjewala further demanded the resignations of Sushma Swaraj and Rajasthan Chief Minister Vasundhara Raje.
"During the UPA government's tenure, the Congress got the then foreign ministers Madhav Singh Solanki and Natwar Singh to resign on moral grounds. Prime Minister Narendra Modi should also follow suit and demand the resignations of Sushma Swaraj and Raje on moral grounds," Surjewala said.
