Constance Marten and Birmingham partner Mark Gordon deny killing their newborn baby

Constance Marten and her partner Mark Gordon have pleaded not guilty to all charges relating to the death of their newborn baby Victoria.

The couple denied the manslaughter of their baby girl at the Old Bailey on Thursday (October 26), the BBC reports.

They also pleaded not guilty to four other charges, including concealment of the baby’s birth, causing or allowing her death and perverting the course of justice by concealing the body.

Mr Gordon, 49, who is from Birmingham, said “not guilty” in a loud voice as the five charges were heard in court.

Ms Marten, 36, also denied all charges saying “Definitely not guilty” to the charge of manslaughter and “absolutely not guilty” to the charges to cruelty and causing or allowing the death of a child.

They appeared before the judge Mark Lucraft KC. The judge at one point during the hearing asked the defendants to stop talking to each other.

Both have been remanded into custody ahead of the hearing on December 8, with the trial date set for January 2. The couple had been missing since January 5 and were arrested in Brighton on 27 February.

Their daughter’s body was discovered on 1 March in a Brighton shed following a lengthy police search.
