We still need a Lockerbie inquiry

[This is the heading over an article on The Guardian's website by Pamela Dix, whose brother was one of those killed in the Lockerbie disaster. It reads as follows:]

For 20 years, UK Families Flight 103 has been campaigning for a full independent inquiry into the events leading up to and after the Lockerbie plane bombing. In the request for an inquiry, the families group has clearly identified the areas of concern and the questions that need to be answered. This request is separate from the need for an independent, criminal investigation to bring to justice those responsible.

The fact that so far the outcome of the criminal investigation has not been conclusive is disappointing. Widespread concern around the safety of the conviction of Abdelbaset al-Megrahi has raised a number of issues. There are also issues about the division of responsibility between Westminster and Holyrood and whether it was right to release Megrahi on compassionate grounds. But everyone is in agreement that whether or not he is guilty, others must have been involved. We hope that the fact that the criminal investigation is to continue will contribute to our quest for the truth.

The circumstances of the trial, the appeal and the Scottish judicial process have prompted calls for a separate inquiry. There is an argument that any such investigation is the responsibility of the Scottish parliament, with the powers to call upon the UK government, and its officers, to explain its position.

However, this is quite separate from the families' continuing call for an independent, wider inquiry. Some of the issues that we wish to see included in such an inquiry relate to national security, foreign policy and transport safety – all responsibilities that since devolution remain within the remit of the UK government. It is galling to listen to David Miliband's off the cuff response to our request for an inquiry: that the biggest mass murder in the UK had nothing to do with his government. If this were the case, why did Robin Cook, Jack Straw and Tony Blair have ongoing discussions with us about a possible public inquiry, both before and after devolution? At no stage was it suggested that this was a matter for the devolved Scottish parliament.

Underpinning our request for this inquiry is our belief that unless we understand and acknowledge the complicated series of events that led to the decision to put a bomb on Flight 103, no lessons will be learned. The fact that Straw told us personally that he would have instigated an inquiry at the time if he had been in a position to do so does not lessen our frustration in failing to get ministers to accept what must be done.

Governments need to understand the tenacity of relatives involved in such tragedies. There have been numerous occasions when we could have caved in under the lack of interest, political pragmatism or sheer ignorance of those in authority. Yet nearly 21 years after the explosion that killed 270 dearly loved people, we have not lost heart that finally – surely – the fourth prime minister to hold that office since the disaster will do the right thing. This is why relatives of those killed on Pan Am 103 stood at the gates of Downing Street to hand over a letter requesting the prime minister, Gordon Brown, to instigate a full public inquiry into the circumstances of the destruction of the aircraft.
