History
After the war, Jack Marshall briefly established himself as a barrister, but was soon persuaded to stand as the National Party's candidate for the new Wellington electorate of Mount Victoria in the 1946 election.

As such, the Prime Minister, Peter Fraser of the Labour Party, amended the regulations. Marshall held the electorate for the three terms of its existence. Through the, he transferred to the electorate. Jack Marshall became Prime Minister in the Second National Government in 1972, after Keith Holyoake retired. He was defeated by Norman Kirk in the 1972 election, and was replaced as leader of the National Party by Robert Muldoon in 1974.
