Stephen Port has appealed against his murder convictions of four men.
Former chef Port, of Barking, east London, was found guilty of killing Daniel Whitworth, 21, and Gabriel Kovari, 22, in 2014.
Inquests into the pairs' deaths before Port's conviction originally recorded an open verdict, but High Court Lord Justice Holroyde said that new inquests were both "necessary and desirable" after new evidence had come to light last year.
Daniel Whitworth and Gabriel Kovari
The body of Slovak-born artist Kovari, was discovered close to a churchyard in Barking on 28 August, 2014.
The body of Daniel Whitworth, from Kent, was found in the same spot less than three weeks later.
Port was also convicted last year of killing Anthony Walgate, 23, Jack Taylor, 25, whose bodies were discovered in an around the same east London churchyard where Daniel and Gabriel's bodies had been found.
Jack Taylor and Anthony Walgate
He was originally handed a life sentence in jail after being found guilty but now the BBC report he has appealed his sentencing.
The appeal is currently in early stages and hasn’t been reviewed by a judge who will have to determine whether it will proceed.
It’s also reported he is only appealing the murder convictions, not the sexual offences.
