1867 to 2011 elections
The arrangements for elections between 1881 and 1903 are not currently shown in the table.
The original constituencies were altered by the Redistribution Act 1893 as follows:
These were used for the 1903, 1908, 1913 and 1919 General Elections. The same constituencies and distribution of seats were also used for the 1934, 1946 and 1951 elections and so are likely also to have been used for the 1924 and 1929 elections.
The distribution of seats was changed for the 1956 election, and again for the 1986 election, as shown.
= sheading, = town
Further back in history, before democratic elections, each of the six sheadings was represented by four members.
