Dr Ralf Speth, Jaguar Land Rover CEO, said: “Innovation in design, engineering and technology is at the core of our business and for the UK, this means we will continue to invest in new products, develop new technologies and enhance the skills of our employees.

“The launch of our latest Jaguar models, including the new XF Sportbrake later this year, means it is a very exciting time for Jaguar. These new models will attract new customers to the brand as we look to expand our global reach and further enhance our position in the market.”

JLR added that the launch of the new models would also support thousands of jobs in the UK supply chain.

Jaguar has seen its sales soar to more than 29,000 vehicles in the first six months of 2012, a 19 per cent increase compared to the same period in 2011..

Welcoming the new jobs, Des Thurlby, HR director at JLR said: “We have embarked on the most ambitious recruitment campaign in the company’s history, hiring 8,000 people in the last two years.

"We provide high quality training and development for all of our employees so this latest announcement for 1,100 jobs is great news for the West Midlands and the UK supply chain.”

Business Secretary Vince Cable, added: “This expansion is a clear demonstration of Jaguar Land Rover’s continuing commitment and investment in the UK.”
