Journalist Shiv Malik’s attempt to have a production order served on him by police resumes at the Royal Courts of Justice this morning. Malik, 27, was ordered to hand over notes, tapes and other materials relating to his book Leaving Al Qaeda, co-authored with former Al Muhajiroun member Hassan Butt.

Butt was arrested by Greater Manchester Police on 9 May, and released without charge yesterday.

Representing Mr Malik, James Eadie QC said that the production order could destroy Malik’s work, which he described as ‘serious journalism shedding light on an issue of the highest public importance.

Malk is being supported by a number of media organisations, including Index on Censorship

The case is scheduled to conclude today.
