Cynllun y Trydydd Sector yw ein prif fframwaith polisi ac mae’r berthynas rhwng Llywodraeth Cymru a’r Trydydd Sector yng Nghymru wedi’i seilio arni.  Mae’n disgrifio bwriadau Llywodraeth Cymru o ran datblygu’r berthynas honno.  Adran 74 Deddf Llywodraeth Cymru 2006 sy’n rhoi’r fframwaith deddfwriaethol i’r polisi hwn.
The Third Sector Scheme is our key policy framework which underpins Welsh Government’s relationship with the Third Sector in Wales and sets out Welsh Ministers’ intentions in taking forward this relationship. Section 74 of the Government of Wales Act 2006 provides the legislative framework for this policy.
