Ed Sheeran has released a song, called F64, in tribute to his friend Jamal Edwards nearly a year after his death.
It has been released on Edwards' music platform SBTV, on which Sheeran rose to fame more than 10 years ago.
Edwards was a lifelong fan of Chelsea FC, with the video for the track filmed at the team's Stamford Bridge stadium.
The DJ and entrepreneur's mum, Brenda Edwards, has also been raising awareness of her son's death by campaigning for more CPR training.
Jamal Edwards died aged 31 from cardiac arrhythmia after taking recreational drugs in February 2022.
