Unison said a reorganisation of local government should not be a pre-condition for regional assemblies to go ahead.
'The guiding principle should be that power is devolved down from central government not taken from local government. It must not mean removing a tier of local government closer to the community.
'It should also be about reducing the number of and power of unelected quangos which spend millions of taxpayers funds with no accountability.
'Unison will work to create a consensus in favour of regional assemblies because we believe they must have clear, popular consent. That support should rest on what they can deliver, not the mere fact of their creation.
'We want public services at the heart of the regional government agenda. The delivery of public services must be overseen by democratic structures.'
