Cytunwyd y byddai Syr Ian, yn hydref 2015, yn paratoi crynodeb ffeithiol o’r dystiolaeth yr oedd ef a’r Panel Adolygu wedi ei chasglu. Bellach mae Syr Ian wedi llunio’r adroddiad hwnnw, a dyma’r adroddiad rwy’n ei gyhoeddi heddiw. Mae’n crynhoi’r dystiolaeth a gafodd ei hystyried gan y Panel Adolygu rhwng mis Ebrill 2014 a mis Medi 2015. Mae’n nodi’r prif themâu sy’n codi ynddi, ond nid yw’n cynnig barn ar ei dilysrwydd na’i harwyddocâd. Nid yw ychwaith yn ceisio cynrychioli barn y Panel na chynnig argymhellion. Bydd y pethau hynny’n rhan o’r adroddiad terfynol, a gyhoeddir erbyn mis Medi 2016.
It was agreed that in autumn 2015 Sir Ian would produce a factual summary of the evidence he and the Review Panel had collected as part of their work.  Sir Ian has now produced that report, which I am publishing today.  The report summarises the evidence considered by the Review Panel from April 2014 to September 2015.  It identifies the key themes arising from this evidence, but does not make any judgement about its validity or significance.  Nor does it seek to represent the Review Panel's views or provide any recommendations.  These will be presented in the final report, which will be issued by September 2016.
