Prime Minister David Cameron, who has promised to renegotiate Britain's EU ties ahead of a vote by the end of 2017, favours staying in a reformed EU but has said he rules nothing out if he cannot get the changes he wants.

All major British car brands, including Jaguar Land Rover, Mini and Bentley (>> Volkswagen AG), are foreign-owned with their parent companies enjoying the benefits of tariff-free trade within the 28-member bloc.

The Society of Motor Manufacturers and Traders commissioned a report last year before it was certain a referendum would take place which showed that 92 percent of members believed their business was better off in a reformed EU.

"Reform is needed, particularly when it comes to better regulation that supports global competitiveness. But we must have a seat at the table to ensure this happens," SMMT President Gareth Jones will say in a speech according to pre-released quotes.

"Be assured, SMMT will make sure the view of the automotive industry is heard."

Jones will also advise the government, which is due to outline a spending review on Wednesday including where cuts will fall in a bid to close Britain's budget deficit, to maintain investment support for business.
