Labour MP David Lammy authored a report which found a surge in the Muslim prison population and found lack of data on why this population has surged. The report was commissioned by David Cameron in 2016. There has been a 50% rise in the share of prisoners who are Muslim in only ten years. Muslims are only 5% of the overall British population but 15% of the prison population.
Lammy notes that the trend is difficult to trace back to its origins because data is not collected on the religious identities of defendants while still in trial. So, it is unclear if the disparity arises in arrests or in sentencing.
Equality and Human Rights Commission chairman David Isaac stressed that the lack of explanation should signal that “we need more transparent data published.”
Dr Zubaida Haque, a researcher for the think tank The Runnymede Trust, said terror convictions cannot account for the size of the rise. Dr Haque also raised concern about Islamophobia within the prison system and in the criminal justice system more broadly.
