Bill English, New Zealand farmer and politician, 39th Prime Minister of New Zealand
Sir Simon William English (born 30 December 1961) is a former New Zealand National Party politician who served as the 39th prime minister of New Zealand from 2016 to 2017 and as the 17th deputy prime minister of New Zealand and minister of Finance from 2008 to 2016 under John Key and the Fifth National Government.

A farmer and public servant before entering politics, English was elected to the New Zealand Parliament in 1990 as the National Party's candidate in the Wallace electorate. He was elevated to Cabinet in 1996 and in 1999 was made Minister of Finance, although he served for less than a year due to his party's loss at the 1999 general election. In October 2001, English replaced Jenny Shipley as the leader of the National Party (and consequently as Leader of the Opposition). He led the party to its worst defeat at the 2002 general election, and as a consequence, in October 2003 he was replaced as leader by Don Brash.

In November 2006, after Brash's resignation, English became deputy leader under John Key. After National's victory at the 2008 general election, he became Deputy Prime Minister and was also made Minister for Finance for the second time. Under English's direction New Zealand's economy maintained steady growth during National's three terms of government. He became a list-only MP after stepping down as an electorate MP at the 2014 general election.

John Key resigned as leader of the National Party and prime minister in December 2016. English won the resulting leadership election unopposed and was sworn in as prime minister on 12 December 2016. In the 2017 general election, National won the largest number of seats but fell short of a majority. The parties holding the balance of power declined to support the existing government, and English was subsequently replaced as prime minister by Jacinda Ardern, leader of the Labour Party. English initially continued on as Leader of the Opposition, but resigned as leader of the National Party on 27 February 2018 and left parliament two weeks later.
