A British woman from an aristocratic family and her partner were Monday jailed for 14 years each for the manslaughter of their newborn daughter, who died while they were living off-grid in freezing temperatures.

Passing sentence Judge Mark Lucraft told Constance Marten, 38, and Mark Gordon, 51, that the way they treated their baby, Victoria, had been "neglect of the gravest and most serious type".
