New Delhi: The government has no hesitation in holding an inquiry on reports of Walmart lobbying in the US to open the way for foreign equity in retail trade in India, parliamentary affairs minister Kamal Nath told Parliament on Tuesday.

Amid ruckus in both houses of Parliament with the Bharatiya Janata Party (BJP) demanding an explanation from the government on the issue, Kamal Nath assured members that the government is "concerned over the issue".

"We have no hesitation in having an inquiry in this and money spent in India. We are open for a discussion and this is matter of concern for the government," he told both houses of Parliament.

"We want to get to the facts of the matter. I would during course of the day make further announcements towards this," he added.

BJP leader Yashwant Sinha in Lok Sabha said that the report in the American senate proves that Walmart spent money in India to enter this country.

"Who were the beneficiaries of the money spent by Walmart in India," asked Yashwant Sinha.

"American system is not opaque as ours and that is the reason Walmart's deeds have come to the fore," Sinha added.

Earlier, proceedings in both houses of Parliament were stalled on Tuesday as the BJP took up the issue of international supermarket chain Walmart lobbying in the US to open the way for foreign equity in retail trade in India.
