 This revised proposal was continued in a further white paper in March 1970 , although this proposed that the counties be unitary authorities which would have no district councils below them . The incoming Conservative government resurrected two @-@ tier local government in a consultative document published in February 1971 , again with the same upper @-@ tier boundaries . Some minor changes having been made to the existing county boundaries due to special local factors , the Local Government Act 1972 duly created Clwyd as a merger of Flintshire with most of Denbighshire , along with the <unk> Rural District from Merionethshire . The 1970 white paper had introduced the name of Clwyd by reference to the River Clwyd and the Clwydian range of hills ; Clwyd was the only new Welsh county which did not take its name from an ancient kingdom .
