Daire

Dara is a name with more than one origin.The origin most accepted is as a male name meaning "Pearl of Wisdom". However, it is often used in Ireland (and the United States), as either a male or a female given name, and it also occurs as a surname. The spelling varies, with variations including Dara, Daire and Darragh. The Irish form is probably derived from doire, the Irish word for "oak tree", though as a surname it may be a version of the Irish name Mac Dubhdara.

Since a distinct U-Turn in MOD policy from centralised repair expertise to diversified line repair, DARA's operations are either scheduled to be closed or under review, with an intended strategy to privatise the various remaining divisions.
