A self-confessed "Snapchat addict" orchestrated the murder of her on-off boyfriend and then posted a video of him dying in a pool of blood, a court heard.

Fatima Khan, 20, is accused of plotting with a rival for her affections to kill Afghan asylum seeker Khalid Safi, 18, who she had been seeing for two years.

Mr Safi was repeatedly stabbed in the chest by Raza Khan in North Acton, north London, on the evening of December 1 2016, jurors were told.

Rather than calling for an ambulance, Fatima Khan allegedly filmed him as he laying dying in the street.

She posted it on Snapchat with the caption: "This is what happens when you f--- with me", the Old Bailey heard.
