The Bharatiya Janata Party (BJP) on Tuesday sought an explanation from Prime Minister Manmohan Singh over the Jet-Etihad deal.
"It seems now there is something wrong in this deal as well. We are not against FDI in aviation, but if there is a scam in FDI, we will oppose it," BJP spokesperson Syed Shahnawaz Hussain said.
"The way the civil aviation minister is pointing towards then PMO and cabinet, the prime minister should clear the situation in front of the country," he said.
The BJP leader compared it with the alleged scandal in allocation of coal blocks.
Objections to the Rs2,058 crore Jet-Etihad deal were first raised by a parliamentary standing committee headed by Communist Party of India-Marxist MP Sitaram Yechury.
After this, senior MPs Jaswant Singh and Dinesh Trivedi, and Janata Party chief Subramanian Swamy also wrote letters to Prime Minister Manmohan Singh over the deal.
