urban development had become clear. For example, in the area that was to become the seven boroughs of the metropolitan county of West Midlands, local government was split between three administrative counties (Staffordshire, Warwickshire, and Worcestershire), and eight county boroughs (Birmingham, Coventry, Dudley, Solihull, Walsall, Warley, West Bromwich, and Wolverhampton). Many county boundaries reflected traditions of the Middle Ages or even earlier; industrialisation had created new and very large urban areas like the West Midlands, Liverpool and Manchester which spanned traditional county boundaries and were now often bigger than and far from their traditional county towns. The Local Government Commission was wound up in 1966, and replaced with a Royal Commission (known as the Redcliffe-Maud commission). In 1969 it recommended a system of single-tier unitary authorities for the whole of England, apart from three metropolitan areas of Merseyside, SELNEC (South East Lancashire and North East Cheshire, now known as Greater Manchester) and West Midlands (Birmingham and the Black Country), which were to have both a metropolitan council and district councils. This report was accepted by the Labour Party government of the time despite considerable opposition, but the Conservative Party won the June 1970 general election on a manifesto that committed it to a two-tier structure. The new government made Peter Walker and Graham Page the ministers, and quickly dropped the Redcliffe-Maud report. They invited comments from interested parties regarding the previous government's proposals. The Association of Municipal Corporations, an advocacy group representing the boroughs, responded to Redcliffe-Maud by putting forward a scheme where England outside London would be divided into 13 provinces, with 132 main authorities below that. The AMC argued that the Redcliffe-Maud units would be too far removed from the people they served, and suggested units that in some places were much smaller in size. The Times gave the example of Kent, which under Redcliffe-Maud would have consisted of two unitary authorities, the smaller having a population of 499,000 (as of 1968), while the AMC proposal would divide the same area into seven local authorities, ranging in population from 161,000 to 306,000. White Paper and Bill The incoming government's proposals for England were presented in a White Paper published in February 1971. The White Paper substantially trimmed the metropolitan areas, and proposed a two-tier structure for the rest of the country. Many of the new boundaries proposed by the Redcliffe-Maud report were retained in the White Paper. The
