The jury in the trial of the aristocrat Constance Marten and her partner, Mark Gordon, over the death of their newborn baby has been discharged after failing to reach verdicts. Marten, 37, and Gordon, 50, were charged after their daughter, Victoria, was found dead on an allotment in Brighton, East Sussex, last March. They had been arrested in Brighton last February after a high-profile police search for the missing baby. Marten and Gordon were each charged with manslaughter by gross negligence, causing or allowing the death of a child, concealing the birth of a child, child cruelty and perverting the course of justice. The two denied all counts and went on trial at the Old Bailey on 25 January. Jurors began deliberating on 30 April and have been discharged after more than 72 hours of deliberation. Marten and Gordon may face a retrial.
