A man accused of killing four soldiers in the 1982 IRA Hyde Park bombing will not be prosecuted because he was given a guarantee he would not face trial.

It follows a judge's ruling that an official assurance given in error meant John Downey could not be prosecuted.

Victims' families said they felt "devastatingly let down".
