An interesting and detailed academic legal article by Kiron Reid, Lecturer in Law at the University of Liverpool, which references this blog in several places:
K. Reid 'Letting Down the Drawbridge: Restoration of the Right to Protest At Parliament'. (2013) 1 Law Crime and History 16 (pp. 16-51) (.pdf) (Internet (free access)). ISSN 2045-9238.
It is an article about the law and history on protest around Parliament, including the ban that was enforced under SOCPA and the new narrower restrictions.
