Bydd yr adolygiad yn dechrau yn y gwanwyn. Yn ystod hydref 2015, bydd Syr Ian yn llunio crynodeb ffeithiol o’r dystiolaeth y mae ef a’i dîm adolygu wedi’i chasglu fel rhan o’u gwaith. Caiff ei adroddiad terfynol, gan gynnwys ei argymhellion terfynol, ei gyhoeddi erbyn mis Medi 2016.
The review will commence this Spring. In Autumn 2015 Sir Ian will produce a factual summary of the evidence he and his review team has collected as part of their work.  His final report, including his final recommendations, will be issued by September 2016.
