Daeth y digwyddiad hwn i ben wrth lofnodi Datganiad Caerdydd; cadarnhawyd hyn gan Gynulliad Cyffredinol y CPMR, sy'n cynrychioli dros 160 o ranbarthau Ewropeaidd, ac fe'i llofnodwyd heddiw gan 20 o arweinwyr rhanbarthol ac awdurdodau lleol Ewrop o'r Alban, Ffrainc, Iwerddon, Sbaen, yr Almaen, Sweden, Norwy a'r Iseldiroedd.
This event culminated in the signing of the Cardiff Declaration; this was ratified by the CPMR’s General Assembly, which represents over 160 European regions, and was signed today by 20 European regional and local authority leaders from Scotland, France, Ireland, Spain, Germany, Sweden, Norway and the Netherlands.
