A rapper who threatened a 'charismatic' charity worker on video before viciously murdering him in front of his young son inside a barber shop has been jailed for life.

Renai Belle was driven by jealousy and rage when he stabbed his former friend Josh McKay in the neck in Leyton, east London, the Old Bailey heard.

Before the fatal attack, Belle had threatened father-of-two Mr McKay, 33, in a rap video after the victim had refused to fund his career.

Following an Old Bailey trial, Belle, 30, of Edmonton, north London, was found guilty of murder and possession of a knife.

On Wednesday, he was jailed for life with a minimum term of 28 years.
