In November 2005, Barton's 17-year-old half-brother Michael was convicted of the race murder of Liverpool student Anthony Walker. Anthony, who was 18 and black, was killed with an ice axe at McGoldrick Park in Huyton, Merseyside, in July 2005.
Joey Barton had made an appeal for his half-brother to give himself up and subsequently gave evidence during the trial. Michael Barton will serve a minimum of 17 years and 8 months behind bars. The Bartons' cousin Paul Taylor was jailed for 23 years and 8 months.
