Durham County Council has backed plans to create a combined authority for the North East as long as several conditions are met.
The council said its decision to support the devolution deal was subject to the county not being financially worse off by the government's proposals on transport and highways funding.
It also wants conditions met in relation to mayoral powers – such as the assurance there will not be a mayoral veto - and an ongoing discussion with Government about fairer funding.
Cllr Simon Henig, leader of the council, said: ‘We believe that devolution offers real opportunities to the North East - and nearly 60% of people in County Durham who responded to our household poll agreed that it could benefit the region.
‘However, there is still some progress to be made and we remain focused on ensuring that the conditions which form part of the agreement are met.’
