Home Office paedophile cover up?

Some 30 years ago, back in 1983, a Conservative MP Geoffrey Dickens passed a bundle of papers to the then Home Secretary Leon Brittan containing allegations of paedophiles within Westminster. Lord Brittan has now confirmed he received a 'substantial bundle of papers’ from Mr Dickens when he was Home Secretary in 1983 and passed them to his officials for investigation.
So far, so good, everybody seems to be in agreement that far, but it is what happened after that seems to be a mystery, although the Home Office has now admitted that the Dickens dossier was subsequently destroyed.
These events have all the makings of a good conspiracy story and it has been announced that the Home Office is to appoint a senior legal figure to carry out a fresh review into how it handled a dossier. Other MPs are now demanding an " an overarching inquiry" into how abusers were allowed to operate within the public services in this country.

We seem to love enquiries in this country, all the way from Bloody Sunday to Hillsborough, Phone Hacking, the Iraq War, Jimmy Savile and now this. I'm sure they are all justified, the cost seems to be many billions and at times one wonders if there is not a better way of dealing with these matters.

The Daily Mail has an interesting piece. To me the more interesting part is not the story of  Sir Peter Hayman, but the attitudes of a large number of prominent people and how they "closed ranks" against this "working-class oik from  the North of England". Many are still around today and it is interesting to read what they said 30 years ago.

Meanwhile, I have a question of my own. If I were handing over a bundle of documents to anyone, I'm certain that I would keep photocopies. Surely an MP who had carried out all these investigations would have kept copies of the papers. So where are they now, or were they, too, destroyed by someone when he died?
