Er mwyn adlewyrchu safle’r Cynllun o ran datblygu cynaliadwy, fodd bynnag, rydym wedi cytuno y bydd cyfrifoldeb am y Cynllun yn cael ei drosglwyddo o’r portffolio Llywodraeth Leol a Chymunedau i bortffolio’r Amgylchedd a Datblygu Cynaliadwy, a hynny o 1 Ebrill 2012.  Hoffem ddiolch i bawb drwy’r wlad sydd wedi cyfrannu at ddatblygu’r Cynllun Gofodol trwy grwpiau’r Gweinidogion a’r swyddogion. Serch hynny, rydym wedi penderfynu diddymu’r strwythurau rhanbarthol sy’n bodoli ar gyfer Cynllun Gofodol Cymru, o ran Gweinidogion a swyddogion. Golyga hyn y bydd y tirlun partneriaethau rhanbarthol yn dod yn symlach o lawer.
However, to reflect the Plan’s locus in sustainable development we have agreed that responsibility for the Plan will move from the Local Government and Communities portfolio to the Environment and Sustainable Development portfolio with effect from 1 April 2012.  We would like to thank everyone  across Wales who has contributed to the development of the Wales Spatial Plan through the Ministerial and official groups but we have decided that the regional Ministerial and officials’ structures relating to the Wales Spatial Plan will be discontinued, representing a significant simplification of the regional partnership landscape.
