India will seek Pakistan-born Lashkar-e-Taiba operative David Coleman Headley's extradition from the United States after the National Investigation Agency files a chargesheet, naming him as an accused in the 2008 Mumbai terror attacks case.
The Centre's assertion came after a 2009 cable sent by then US ambassador Timothy J Roemer, released by Wikileaks, quoted then national security adviser MK Narayanan describing India's demand for Headley's extradition as "political posturing".
Home minister P Chidambaram had recently declared that the NIA would soon file a chargesheet against Headley once the last bits of information needed by them are received.
Home ministry sources said the chargesheet would form the legal basis for Headley's extradition. But officials are sceptical about Washington playing ball.
They believe that the US may not be prepared to provide unrestricted access to him.
