The Ministry had asked the firm last week to provide details about its transactions with Tunisia and India-based firms IDS Infotech and Aeromatrix.
The Italian firm had sought a week's extension to explain its linkages with the two firms and teh request has been granted by the Defence Ministry. AgustaWestland has been asked to furnish their clear replies within this stipulated time-period, highly-placed sources told PTI here.
A show cause notice was issued by the Defence Ministry to AgustaWestland last month as part of the process to cancel the contract for 12 VVIP choppers.
The Ministry had asked the firm why the deal should not be cancelled in view of corruption charges against it.
The firm had replied to the letter denying any wrongdoing in the deal but Defence Minister A K Antony rejected the response of the firm.
