British Premier David Cameron has assured Prime Minister Narendra Modi of the UK’s “firm support” for India’s NSG membership bid, a boost to the country ahead of the nuclear trading club’s crucial meeting next week. Cameron confirmed Britain’s backing for India’s membership of the 48—nation Nuclear Suppliers Group (NSG) in a telephone call to Modi on Thursday.

A Downing Street spokesperson said, “The Prime Minister spoke to Narendra Modi about India’s application for membership of the Nuclear Suppliers Group, a group of nuclear supplier countries that works together to prevent nuclear proliferation by controlling the export of materials, equipment and technology that can be used to manufacture nuclear weapons.”
