Arriving here within days of exposure of the Rs 3,600-crore VVIP helicopters scam involving Anglo-Italian firm AgustaWestland, UK Prime Minister David Cameron is likely to be pressed for more information in this regard during his meetings with the leadership on Tuesday.
The visit also comes in the wake of India taking steps to scrap the contract after Italian investigators probed allegations that aerospace group Finmeccanica, the parent company of AgustaWestland, had broken the law by paying bribes to foreign officials.

Cameron's trip also comes close on the heels of a visit by French President Francois Hollande here to drum up trade, underlining the growing importance of the Indian economy.
Ahead of the visit, the UK Prime Minister said he wanted the relationship between Britain and India to be "one of the great partnerships of the 21st century".
