 "Govt has sought 'full assistance' from UK on chopper probe: PM")
Singh was speaking alongside British Prime Minister David Cameron, who is on a three-day visit to India to push trade ties amid a corruption row over a Rs 3,600-crore deal for a dozen AgustaWestland helicopters.
After having wide-ranging talks which included key issues of nuclear energy cooperation, security, terrorism and trade with Cameron, Prime Minister Manmohan Singh said he conveyed India's "serious concerns" pertaining to the chopper scam and sought his "full assistance" on the issue.
"I told him that we have sought an explanation from the company by February 22 to examine if the contractual provisions on unethical practices and the Integrity Pact have been violated. I have sought full assistance from the UK in this case. Prime Minister Cameron has assured me of the cooperation of his Government in the investigations," PM said.
Cameron, speaking after Singh, said his government would respond to any request for information about the deal.
Singh also said that the two sides have also decided to commence negotiations on a bilateral Civil Nuclear Agreement.
