India on Friday said it had not received any proposal from Pakistan on President Pervez Musharaf's offer of free movement across the Line of Control in Jammu and Kashmir and any action can be initiated only when it receives a formal proposal.

"We have not received any official proposal from Islamabad to this effect," Defence Minister Pranab Mukherjee told newsmen on the sidelines of the Naval Commanders conference in New Delhi.

"Only when we receive the offer at official level, we can initiate any action," he said.

On the recent agreement with France on building of six Scorpene submarines under technology transfer, Mukherjee said this would give a strategic boost to the country by reopening underwater vessel manufacturing capability within the country.

On Navy's 20-year Perspective Plan to boost submarine strength to 24, the Minister said India would take a decision at an appropriate time on the offers of building other submarines.
