Sir Harry is calling on the Welsh Assembly to shelve plans for any further structural changes.
He criticised debate over political structures, saying: 'It is time to let local government deal with the weight of legislation . . . I have always viewed political structures as a means to an end, the real prize being the development of community leadership.'
A spokesman for the Assembly said there are no plans for further structural change at councils.
Sir Harry said there is tension between local government and the Assembly, and he called for a 'mature partnership based on trust, respect and consultation'.
