This week Conservative MP for Beaconsfield, Dominic Grieve, writes to Bucks Free Press readers:

No matter what else was happening at Westminster recently, the independent report about Iraq which was published by Sir John Chilcot on July 6 merited the complete concentration and serious consideration which it received from the House of Commons.

Much has been said about the duty and compassion which we all owe to the families of those service people who lost their lives in this conflict.

Their grief and sacrifice has been great and they waited a long time to hear the outcome of the inquiry.

But I am sure that they would be the first to say that they share the sadness of people in Iraq and across the wider Middle East who have borne the consequences of the decision to go to war.

One of the conclusions reached by Sir John Chilcot was that the process by which the decision to take military action was flawed: in his opinion, not all the diplomatic options were exhausted by the time that military action was decided upon.

In the Commons on July 6, I said that the conclusions of the inquiry, into the way that legal advice and intelligence was processed, and intelligence used to inform policy, are pretty damning.

No human institution is ever perfect and by nature they cannot be perfectible. But from my own experience as Attorney General and now as chairman of the Intelligence and Security parliamentary committee I can say that changes have been implemented since that time.

Because no system can ever be perfect I would like to see sufficient scrutiny and subsequent review, to ensure that lessons can be learned when mistakes are made.

This is not a simple, formulaic process, but improvements can be made and we have to learn when errors happen.
