Solihull Council has voted in favour of joining the West Midlands Combined Authority as a constituent member.
The council said the combined authority offered a ‘once in a lifetime’ opportunity to push for power over economic growth, skills and connectivity.
Cllr Bob Sleigh, leader of Solihull Council, said: ‘The WMCA will create a clear regional voice to insist that the decisions that affect the region should be made here, in the region; not in Whitehall.
‘The WMCA’s priorities revolve around improving skills, connectivity and economic growth. They chime exactly with our vision in Solihull for achieving sustainable economic development within the borough and offer us our ‘economic plus’ dividend.’
The combined authority also consists of Birmingham, Coventry, Dudley, Sandwell, Walsall and Wolverhampton, and has submitted a £8bn devolution bid to the Government.
