Roedd Llythyr Asesu Gwelliant gan yr Archwilydd Cyffredinol i’r Cyngor ym mis Hydref 2013 yn egluro bod arweinyddiaeth a gwneud penderfyniadau ym Mlaenau Gwent yn anghyson, ac nid oedd y Cyngor wedi gwneud unrhyw beth fel mater o frys i ymdrin â’i sefyllfa ariannol ddifrifol  a pherfformiad newidiol gan wasanaethau.
The Improvement Assessment Letter from the AGW to the Council in October 2013 made it clear leadership and decision-making in Blaenau Gwent were inconsistent, and the Council had not put in the work to address its serious financial position and variable service performance with the necessary urgency.
