The state is divided into 77 counties that govern locally, each headed by a three-member council of elected commissioners, a tax assessor, clerk, court clerk, treasurer, and sheriff. While each municipality operates as a separate and independent local government with executive, legislative and judicial power, county governments maintain jurisdiction over both incorporated cities and non-incorporated areas within their boundaries, but have executive power but no legislative or judicial power. Both county and municipal governments collect taxes, employ a separate police force, hold elections, and operate emergency response services within their jurisdiction. Other local government units include school districts, technology center districts, community college districts, rural fire departments, rural water districts, and other special use districts.

As the economic situation worsened MacDonald agreed to form a "National Government" with the Conservatives and the Liberals. On 24 August 1931 MacDonald submitted the resignation of his ministers and led a small number of his senior colleagues in forming the National Government together with the other parties. This caused great anger among those within the Labour Party who felt betrayed by MacDonald's actions: he and his supporters were promptly expelled from the Labour Party and formed a separate National Labour Organisation. The remaining Labour Party MPs (led again by Arthur Henderson) and a few Liberals went into opposition. The ensuing 1931 general election resulted in overwhelming victory for the National Government and disaster for the Labour Party which won only 52 seats, 225 fewer than in 1929.
Who was expelled from the National Labour Organisation?
