Cyhoeddais Ymchwiliad Cwnsler y Frenhines ar 10 Tachwedd 2017 gan ddefnyddio fy mhwerau o dan adrannau 48 a 71 o Ddeddf Llywodraeth Cymru. Yn dilyn hyn, rhoddais gylch gwaith pendant i'r Ysgrifennydd Parhaol wneud trefniadau gweithredol i fwrw ymlaen â hyn ar y sail na fyddai'n ymchwiliad cyhoeddus, ac y byddai’n rhaid i gyfrinachedd yr achwynwyr gael blaenoriaeth. Nodais yn glir, ar y sail hon, y dylai'r ymchwiliad gael ei gynnal hyd braich oddi wrthyf fi a'm swyddfa.
I announced the QC Investigation on 10 November 2017, using my powers under s 48 and s 71 of the Government of Wales Act. Following this, I gave the Permanent Secretary a clear remit to make the operational arrangements to take it forward on the basis that it would not be a public inquiry, and that the confidentiality of the complainants must take precedence. I made it clear that the implementation of the investigation on this basis should take place at arm’s length from me and my office.
