Michael Adebolajo, who was given a whole-life sentence for the murder of soldier Lee Rigby has launched an appeal against his sentence.
Adebolajo, 29, together with Michael Adebowale, 22, drove into Fusilier Rigby with a car before hacking him to death in Woolwich, south-east London.
At the time judge, Mr Justice Sweeney, said Adebolajo’s was a “rare case” which warranted a whole-life term.
The Muslim converts had “butchered” the 25-year-old soldier, he said.
In court Adebolajo from Romford, east London denied murder, and described the killing as a “military operation”, claiming that he was a “soldier of Allah”.
But after hearing about the attack on 22 May last year, the jury took 90 minutes to find them both guilty.
Adebowale from Greenwich, south-east London, received a minimum of 45 years in prison.
But both men were found not guilty of attempting to murder a police officer at the scene.
