Caerphilly, Newport, Torfaen and Bridgend councils have given their backing to the proposed £1.2 billion Cardiff Capital Region (CCR) City Deal.
All local authorities in favour of the deal are expected to meet before 10 February 2017 to vote on the plans, and approve a commitment by the group to borrow a combined total of £120 million as part of the CCR City Deal Wider Investment Fund.
The ten local authorities are Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Merthyr Tydfil, Monmouthshire, Newport, Rhondda Cynon Taf, Torfaen, and Vale of Glamorgan.
