I made sure that the House of Lords' Select Committee had sight of it during their deliberations, but it has not, to the best of my knowledge, been published openly before. And yes, the words I have posted are exactly as they appear in his letter (barring the odd possible typo on my part).
I had heard that an attempt was made to have all copies of this letter destroyed - if anyone can corroborate this, please let us know!
