'What you did towards baby Victoria... can only be described as neglect' - judge

The judge says it will take a bit of time to read what he has to say, and he tells Marten and Gordon they can remain seated.
As soon as he started reading out his remarks, Constance Marten was shaking her head.
Her mother, who was here earlier in the day, has not returned to the court room for the sentencing.

Marten and Gordon are back in the dock.
They are leaning towards each other and are in an intense chat.

The judge has a number of options when passing sentence. He can pass a normal (determinate) sentence, or he can pass an 'extended' sentence which has an extra element, or a life sentence.
If he passes a determinate sentence, then Constance Marten and Mark Gordon will have to serve two-thirds of that sentence before being considered for parole.
So for example if he gives a 12-year sentence the couple could not be released for at least 8 years minus the two and a half years they have already served while awaiting trial.

After the judge left court, Marten tried to again give Gordon a note as they were being escorted from the dock.
It was taken off her by a dock officer.
Earlier in the proceedings, the judge admonished the pair for passing notes, saying it was distracting and showed a "complete lack of respect".

Barrister Tom Godfrey says "Ms Marten has paid the ultimate price".
"There was no indication her harm was intentional."
He is asking for a determinate sentence on Marten.

Constance Marten's barrister Tom Godfrey says "the sorrow that Constance Marten feels is impalpable".
"She has, ever since an early stage, accepted that her baby died as a result of something she did. That fact weighs very heavily on her conscience and will do so for the rest of her life".
Godfrey argues that Marten is suffering from C-PTSD (Complex Post-Traumatic Stress Disorder).

Marten and Gordon are in the dock, and there's been more commotion. Marten tried to pass another note to Gordon and the dock officer snatched it back, suggesting she wasn’t allowed to.
Court is back in session.
As a reminder, Constance Marten and Mark Gordon are due to be sentenced today after being convicted of gross negligence manslaughter. They will also be sentenced for other offences including child cruelty.

Disruption in the dock
Constance Marten and Mark Gordon have been passing notes, distracting the judge and leading him to tell them it "shows a complete lack of respect".
Despite threatening to continue without the defendants present, he was distracted a second time. The judge is being much freer of his criticism of the pair today, as he doesn't have to worry about influencing the jury now, writes Daniel Sandford.

Once the judge left the court there was a commotion in the dock.
Marten tried to hand Gordon a piece of paper and the dock officer took it from her.
"Don't snatch it off me, are you alright?" Marten said crossly to the dock officer.

In a letter provided by Marten's mother to the court, she describes her daughter growing up as "inquisitive" and "adventurous".
She says her daughter was "bright" with a "feisty spirit".
"At school she was loyal to her friends", Marten's mother says, adding that "alongside her strength she also carried her fragility" and at times "struggled with confidence and self worth".
Marten's mother adds that she "was horrified by the way the court and newspapers portrayed her".
As Tom Godfrey reads out Marten's mother's letter to court, Marten shows no reaction from the dock and doesn't look over to her mother who is sitting in the well of court.
The hearing has now been adjourned for a lunch break and will be back at 14:00.

Tom Godfrey is now reading out letters in support of Marten.
One is written by someone who first met Marten as a teenager in Uganda where she was volunteering.
The friend described Marten as "someone who acts with integrity and kindness towards others".
A former family housekeeper Cecilia Dubuyer, writes that she remembers Marten as as a "sweet thoughtful young woman" with a "kind heart".

Godfrey, continuing to speak about the death of baby Victoria, says "we accept the court is likely to find that Ms Marten had ignored earlier warnings".
But, he says the warnings do not show that she had a blatant disregard for a very high risk of death of Victoria.
But Godfrey is stopped by the judge, who has spotted disruption in the dock again. He asks Marten what it is about his warning that she does not understand.
Marten speaks from the dock and says that a dock officer is not allowing her to make notes.
The judge says: "You are entitled to a pen... it's very distracting when I am trying to listen to what you are saying on behalf of Miss Marten," directed to Godfrey.

The judge has just told off Constance Marten and Mark Gordon for passing notes.
He tells them it "shows a complete lack of respect", not just to him, but also to Marten's barrister who is making submissions on her behalf.
He threatens to continue without the defendants present if the note-sharing carries on.
Daniel Sandford
Reporting from the Old Bailey
Tom Godfrey, representing Marten, says he agrees that gross negligence manslaughter is the "lead offence", and that the other sentences should be "concurrent".
That means they should be served at the same time.
He says there shouldn't be further uplift on the sentence due to the other offences.
"We say this was not a very serious example" of gross negligence manslaughter, Godfrey tells the court.

Marten's barrister asks the judge to accept the account given in evidence by Marten about Victoria's death and points out the lack of pathological evidence for the baby dying from hypothermia.
As a reminder, Marten has maintained that she fell asleep on the baby in the tent they were living in and woke to find that Victoria had died. Marten and Gordon said it was a tragic accident.
Godfrey submits that the judge should sentence Marten on the basis of smothering.
