The speaker can be opposed at a general election. Three speakers, Groom in 1929, Nairn in 1943 and Aston in 1972 have been defeated at general elections. Because the speaker is always a member of the governing party, they have not continued as speaker following a change of government. The opposition sometimes selects one of its own members for speaker after a general election. This is a symbolic act, and the governing party always supports its own candidates.
