Following reports in Italy on investigation in the alleged scam in a defence helicopter deal with Italian firm Finmeccanica, the government has made a fresh request for information in the matter.
The defence ministry has issued a show cause notice to AgustaWestland asking it to explain within seven days the bribery allegations. The notice also asked the company why the deal should not be scrapped.
