MCC , Middlesex County Council x Middlesex County Council

In 1888 the Local Government Act provided for the establishment of county councils, with constitutions on the lines of a borough council. County Councils were constituted of aldermen and councillors, the councillors being directly elected by the local government electors (for which purpose each county was divided into electoral divisions), the aldermen being elected by the councillors, the proportion being one alderman for three councillors. The aldermen and councillors held office for six years and three years respectively. There is, however, no mayor - the aldermen and councillors are required to elect a Chairman who held office for one year and could be re-elected, but who did not have to be an elected councillor. A vice-chairman was also elected from the members of the county council.

The boroughs and urban districts from which councillors were elected in 1889 were: Staines, Sunbury, Feltham, Stanwell, Uxbridge, Hillingdon, Hayes, Norwood, Heston, Hounslow, Isleworth, Twickenham East, Twickenham West, Teddington, Hampton, Brentford East, Brentford West, Ealing North, Ealing South, Chiswick, Turnham Green, Acton North, Acton South, Hanwell, Harrow-on-the-Hill, Harrow, Pinner, Willesden West, Willesden East, Kilburn North, Kilburn South, Hendon, Friern Barnet, Finchley North, Finchley South, Highgate, Hornsey, Finsbury Park, South Hornsey (Brownswood Park), South Hornsey (Milton Road), Tottenham Lower, Tottenham Middle, Tottenham High Cross, Tottenham Saint Ann's, Tottenham West Green, Edmonton North, Edmonton South, Southgate North, Southgate South, Enfield East, Enfield Central and Enfield West.

At one of the first Council meetings in March 1889 the formation of Committees was considered. Councillors were elected to the Finance, Highways, General Purposes, Parliamentary, Asylum, Contagious Diseases (Animals) Act and Standing Joint Committees. The introduction of new legislation made ever increasing demands upon the Council, involving in later years monthly meetings of some 50 committees and sub-committees.
