UK car manufacturer Aston Martin has announced it is to invest £20 million to expand its operations at its Gaydon facilities.

Some 250 new jobs are to be created by the expansion of the facilities, which are being developed in order to support the roll-out of new models. These will be in engineering, manufacturing and commercial functions.

Aston Martin is to build a new chassis and pilot build facility, new offices, and an extension of the parts and logistics storage area.

The company will also welcome 14 new graduates into its workforce during 2014.

Aston Martin chief financial officer Hanno Kirner said: "The investment in our Gaydon HQ forms part of our long-term strategy which is focused around being the number one British luxury sports car brand."

He described the investment as the biggest in the 101-year history of Aston Martin.

Major development work is due to be completed in 2015.
