Camberley, Dec. 15 (Reuters): Britain’s Prince William, eager to draw a line under a decade of conspiracy theories about his mother’s death, is to graduate as an army officer today and launch his new career.

The second in line to the throne is to pass out at the elite Sandhurst military academy before his grandmother, Queen Elizabeth, in a ceremony famed for its military pomp and circumstance.

William takes to the parade ground just a day after a British police inquiry ruled that his mother, Princess Diana, was not the victim of a murder plot when she and her lover were killed in a high-speed car crash in Paris in 1997.
