The father of 14-year-old Molly Russell has called for urgent changes to make children safer online after an inquest found social media content contributed "more than minimally" to her death.

Coroner Andrew Walker concluded Molly, from Harrow, died from an act of self-harm while suffering depression and the negative effects of online content.

He said the images of self-harm and suicide she viewed "shouldn't have been available for a child to see".

Molly took her own life in 2017.

After the hearing finished on Friday, Molly's father Ian Russell said: "It's time to protect our innocent young people instead of allowing [social media] platforms to prioritise their profits by monetising the misery of children."

In a statement, NSPCC chief executive Sir Peter Wanless said: "This should send shockwaves through Silicon Valley - tech companies must expect to be held to account when they put the safety of children second to commercial decisions.

"The magnitude of this moment for children everywhere cannot be understated."

Mr Walker, the senior coroner for north London, said Molly appeared a healthy girl who was flourishing at school, having settled well into secondary school life, and displayed an enthusiastic interest in the performing arts.

However, Molly had become depressed, something common in children of this age, the coroner said.

The inquest was told her condition worsened into a depressive illness.

Mr Walker told North London Coroner's Court: "It would not be safe to leave suicide as a conclusion.

"She died from an act of self-harm while suffering from depression and the negative effects of online content."

His narrative conclusion continued: "Molly subscribed to a number of online sites. She had access to images, video clips and text concerned with self-harm and suicide, or that were otherwise negative or depressing in nature."

'Life-sucking content'

He said that the platforms Molly accessed, Instagram and Pinterest, used algorithms, which resulted in "binge periods" of material, some of which was selected and provided without Molly requesting it.
