The Chief constable of West Midlands police has been ordered to produce information, in response to a claim that the force may have been tipped off in advance of the Birmingham pub bombings, by an IRA mole.
A coroner made the order after hearing legal submissions about whether there was enough evidence to reopen inquests into the 21 people who died.
Chris Halpin reports.
A coroner will today hear a petition from relatives of people who died in the Birmingham Pub Bombings to re-open the original inquest.
John Rowlands died in the attacks in 1974 - his son Paul is among victims' families calling for an inquest into their deaths to be reopened.
