It is a very substantial piece of work and I am grateful to the Committee, their staff, expert group members and supporting research teams for their efforts.
Mae'n ddarn pwysig iawn o waith ac rwyf yn ddiolchgar i'r Pwyllgor, i'w staff, i aelodau'r grŵp arbenigol a'r timau ymchwil a fu'n eu cynorthwyo, am eu hymdrechion.
