Gideon Moshe Sa'ar is an Israeli politician who has served as the Deputy Prime Minister and Minister of Justice since June 2021. Sa'ar previously served as a member of the Knesset for the Likud between 2003 and 2014, and was the Education Minister and afterwards the Minister of the Interior, from 2009 to 2014. In 2019 Sa'ar returned to the Knesset and unsuccessfully ran against longtime leader Benjamin Netanyahu for the leadership of the Likud; he left the Knesset the following year after establishing a new party called New Hope.
Sa'ar worked as an aide to the Attorney General between 1995 and 1997, and then as an aide to the State Attorney until 1998. Sa'ar was appointed cabinet Secretary in 1999 and again from 2001–2 after Likud's Ariel Sharon won a special election for Prime Minister. In the 2003 elections he won a seat in the Knesset on Likud's list, and was appointed Likud Parliamentary Group Chairman as well as Chairman of the Coalition. He was opposed to Israel's unilateral disengagement plan, and attempted to pass a bill demanding a referendum on the subject.
After retaining his seat in the 2006 elections he was reappointed Group Chairman and also became a deputy Knesset speaker.
While in the Knesset, Sa'ar proposed bills to jail employers who fire pregnant women, (he chaired the Knesset Committee on the Status of Women) and to ban cosmetics testing on animals.
In December 2008 Sa'ar won the Likud primaries for its list going into the 2009 elections, giving him second place on the Likud list after leader Binyamin Netanyahu. He retained his seat, and was appointed Minister of Education on 31 March.
In 2012, he again gained the most votes in Likud primaries, and entered the 19th Knesset.
In September 2014, Sa'ar announced that he would be resigning his post before the next election. He said he would still remain a member of the Likud. On 17 September, he took a hiatus from politics. He left the Knesset on 5 November, and was replaced by Leon Litinetsky.
On 3 April 2017 Sa'ar announced his return to politics and intention to run in the next Likud primaries. He was seen as a potential candidate for party leadership and eventually prime minister.
In September 2017, The Jerusalem Post ranked him 5th on its "50 most influential Jews" list, calling him the "heir apparent to the Likud throne". In September 2018, he was ranked 25th along with fellow Likud members Yisrael Katz and Gilad Erdan.
In December 2020, Sa'ar announced that he would leave Likud and will form his own party, called New Hope. He submitted his Knesset resignation on 9 December, which went into effect on 11 December. The party contested the 2021 Israeli legislative election, with the intent of forming a governing coalition, and removing Netanyahu from office. He regained his seat in the Knesset, as New Hope gained six seats at the elections.
In June 2021, Sa'ar became Minister of Justice in the thirty-sixth government of Israel.
