Constance Marten, who was jailed for causing or allowing the death of her newborn baby daughter following a nationwide manhunt with her partner, has been granted permission to appeal against her 14-year sentence. The case attracted intense public attention after Marten and her partner, a convicted rapist, evaded police for weeks while on the run with their baby, who was later found dead. The appeal represents the next stage in a legal saga that has already seen lengthy criminal proceedings and widespread scrutiny of the couple's actions.

Marten was convicted over the death of her fifth child after the infant died while the pair were living in makeshift conditions during their time evading capture. Her legal team has now secured the right to challenge the length of the sentence handed down, meaning the case will return to court for further legal argument rather than being concluded with the original ruling.
