Lancashire MPS will meet the Prime Minister on Monday for crunch talks about a BAE Systems export deal to India.
Conservatives Mark Menzies, Ben Wallace, Nigel Evans and Lorraine Fullbrook will meet Mr Cameron at Downing Street to stress the importance of the deal and government trade support.
It follows an announcement last week a French firm has secured preferred bidder status with the Indian government for a key contract to supply fighter jets.
The MPs will be pressing the Prime Minister for more support for BAE’s Typhoon fighter bid.
The aircraft are built at BAE’s base in Warton, near Kirkham.
Fylde MP Mr Menzies said: “Military experts tell me the Typhoon is by far the best aircraft in its class thanks to the tremendous work of BAE employees in my constituency.
“I have been talking to senior figures at BAE, in the government and in the industry to press the case.
“It is clear the Prime Minister, who has visited India personally, is as keen as I am to help to secure a deal and we will discuss this in greater detail on Monday.”
