A public inquiry into allegations that the death of loyalist prisoner Billy Wright may have been the result of collusion will be published later today.

The leader of the Loyalist Volunteer Force (LVF) was shot dead in the Maze prison in December 1997.

The murder was carried out by three members of the Irish National Liberation Army (INLA).

Since then questions have been raised as to how Wright could have been murdered inside a high-security prison.

In 2004 retired Canadian judge Peter Cory recommended a public inquiry.

He said he was satisfied that "there was sufficient evidence of collusive acts by prison authorities to warrant the holding of such an inquiry".

That investigation was established in May 2007 under the chairmanship of Lord Ranald MacLean.
