Abdallah, who moved to the UK as a child and grew up in south Manchester, was paralysed from the waist down while fighting in the 2011 Libyan revolution.
The Parole Board said: “Following four oral hearing days and a dossier of evidence of over 1,800 pages, we can confirm that a panel of the Parole Board refused the release of Abdalraouf Abdallah.
“Parole Board decisions are solely focused on what risk a prisoner could represent to the public if released and whether that risk is manageable in the community.
“The panel of the Parole Board were not satisfied that he no longer posed a risk to the public, and accordingly did not direct his release.”
The Board explained that “due to the nature of his extended determinate sentence, law determines that he will be automatically released when his sentence expires”.
It said the “sentence expiry date in November is determined by the period of punishment set by the sentencing judge”.
