This area was based on the seven county boroughs and four other non-county boroughs and urban districts around the fringe of the conurbation – Aldridge-Brownhills, Halesowen, Stourbridge, and Sutton Coldfield. The area was divided into seven new metropolitan boroughs – Aldridge-Brownhills was added to Walsall; Halesowen and Stourbridge to Dudley and Sutton Coldfield to Birmingham. A new borough of Sandwell was formed by the merger of West Bromwich and Warley, Solihull took in much of the suburban fringe to the east of Birmingham and the gap between Solihull and Coventry, whilst Wolverhampton and Coventry themselves were taken in more-or-less unaltered.
