Bydd y Cynulliad yn cofio i Archwilydd Cyffredinol Cymru ganfod gwendidau difrifol iawn o fewn y Cyngor ym mis Gorffennaf 2009: ymddygiad gwael ymysg yr aelodau, cydberthnasau gwan rhwng aelodau a swyddogion, cynllunio strategol annigonol a dim llawer o ymgysylltu â’r cyhoedd. Argymhellodd yr Archwilydd Cyffredinol ein bod yn ymyrryd er mwyn helpu i sicrhau adferiad, a fis yn ddiweddarach fe gyfarwyddodd Brian Gibbons y Cyngor i ymdrin â’r holl broblemau y tynnodd yr Archwiliwr Cyffredinol sylw atynt o fewn 18 mis. Hefyd, fe dynnodd rai swyddogaethau oddi ar y Cyngor, ac fe benododd Reolwr Gyfarwyddwr dros dro a Bwrdd Adfer er mwyn monitro datblygiad y Cyngor.
The Assembly will recall that in July 2009 the Auditor General for Wales identified very serious failures within the Council: poor behaviour by members, weak relationships between members and officers, inadequate strategic planning and low levels of public engagement. The Auditor General recommended that we intervene to help secure recovery, and a month later Brian Gibbons directed the Council to address all of the problems that the Auditor General identified within 18 months. He also removed certain functions from the Council and appointed an interim Managing Director and a Recovery Board to monitor the Council’s progress.
