NEW DELHI: An unfazed Subramanian Swamy continued with his bizarre allegations against Congress president Sonia Gandhi and her son Rahul, now calling them " commission agents " and claiming their combined worth now stands at a whopping Rs 2.50 lakh crore.

Swamy has also wondered if Rahul is a Turkish citizen, days after he accused the Congress vice-president of holding a British passport, an allegation that the Sonia Gandhi-led party had rejected "with the contempt it deserves and the falsehood it seeks to perpetuate".

At a press conference in Ahmedabad on Thursday, the BJP leader said Sonia and Rahul "get commission" through the directors of the companies, including "one in France which supplies submarine parts worth Rs 20,000 crore" to India. Swamy did not name the company nor has The Times of India verified those claims so far.

" Rahul Gandhi is not a political leader but a commission agent... All Congress leaders are commission agents," Swamy said.

"Rahul started many companies to get commission... I will enquire whether he has the citizenship of Turkey and other countries or not," Swamy said, adding that the mother-son duo "own wealth worth Rs 2.50 lakh crore, which is more than the Income Tax revenue of the country".

On Monday, Swamy, in a letter to Prime Minister Narendra Modi, had alleged that Rahul had declared himself as a British national in the annual return of a company called Backops Limited in Britain. The company was incorporated in 2003 and dissolved in 2009. He demanded that Rahul be stripped of his Indian citizenship.

"Gandhi has given his date of birth correctly but has declared himself to be of British nationality with a UK address," Swamy's letter to Modi said. It said the Congress leader has "prima facie, committed an unconstitutional act and therefore be liable to be stripped of his citizenship and membership of the Lok Sabha".

Responding to the allegation, Congress spokesperson Randeep Singh Surjewala had said: "Frustrated by their humiliating defeat in Bihar elections and internal revolt brewing among the senior-most leadership, BJP's dirty tricks department led by Subramanian Swamy is resorting to petty and mindless mud-slinging."

"From the day he was born, Rahul Gandhi has held the Indian citizenship and the Indian passport and has never held citizenship of any other country nor has he represented as such. The allegation by Swamy is entirely false," he said.
