A commentary in The Telegraph claimed that before 1926, MPs had to win a by-election to join the government. This got me rather perplexed.
Mr Johnson has sensibly stopped short of joining Labour in pushing for an almost complete ban on second jobs, though it should be pointed out that being a government minister is also paid employment that keeps an MP away from his or her “main job”, whatever that is supposed to be. Long ago, this used to be acknowledged since MPs were not paid at all and, until 1926, if they wanted to join the government they had to win a by-election.
Why would MPs need to win a by-election to join the government? Am I understanding this paragraph wrong?
