Knesset,
Yesh Atid and
Israel Resilience announced that they would form an alliance for the upcoming election.
Gabi Ashkenazi, also a former chief of staff, would join the list in the fourth spot. Blue and White won 35 seats in the
April 2019 Israeli legislative election, the same as
Likud, and conceded defeat. President
Reuven Rivlin tasked
Benjamin Netanyahu with forming a governing coalition, but failed. This triggered the

2020 Israeli legislative election, Blue and White won 33 seats, placing it second after Likud which had 36. The alliance showing strong support in many areas,including
Tel Aviv and
Haifa. On 8 March 2020,
Avigdor Lieberman gave Gantz his backing to form a new government. The next day, the Joint List agreed to work with Gantz and Lieberman to oust Netanyahu. As of 10 March 2020, it remained unclear whether Gantz would be able to gain sufficient MK votes to form a government, as Labor-Gesher-Meretz MK
Orly Levy announced she would not support a minority government and left the Labor-Meretz alliance. An aide also stated that Gantz plans to form a government by 23 March. Lieberman and Labor party leader
Amir Peretz also reaffirmed on 11 March that an alliance with the Joint List would not change their position on forming a political alliance with Gantz. On 15 March 2020, 61 of the 120 MKs told Israeli President
Reuven Rivlin that they would back Gantz as Israeli Prime Minister, which resulted in Rivlin announcing that he had asked Gantz to form the new government. However, Lapid's Yesh Atid and Ya'alon's Telem asked to split from the Israel Resilience Party, and requested that the two parties keep the name Blue and White as the name of their recreated political party. On 27 March 2020, it was revealed that a major obstacle to a potential long-term alliance between Gantz and Netanyahu emerged with regards to implementing U.S. President Donald Trump's Middle East peace plan. Barak Ravid of Israel's Channel 13 news revealed that Gantz, despite previously claiming that he wanted to implement this peace plan, still wanted to hold peace talks with the Palestinians, which Trump and Netanyahu still opposed. Ravid stated that this would likely make the upcoming deal between Gantz and Netanyahu short-lived. As part of the proposed coalition deal between Netanyahu and Gantz, Gantz would replace Netanyahu as prime minister of Israel in 18 months. Subsequently, after long negotiations, a compromise deal was reached over the peace plan. On 6 April 2020,
Amir Peretz, leader of the
Israeli Labor Party, announced that his party might be merging with Blue and White. On 20 April 2020, the coalition deal was officially signed, with Blue and White having an equal number of ministers as the Right. Blue and White received the Justice, Economy, Labor and Welfare, Communications, Agriculture, Culture and Sports, Absorption, Tourism, Minorities, Diaspora, Science and Space, Strategic Affairs, and Social Affairs ministries. The positions of foreign minister, energy minister and environmental protection minister will rotate upon the change of prime minister. The terms of the agreement also provide that Gantz serve as defense minister when the new government is sworn in. On 30 April, the bill approving the new coalition government was given its first approval in Knesset. On 6 May, the coalition agreement was approved by the
Israeli Supreme Court. The same day, both Blue and White and Likud issued a joint statement claiming that the new unity government would be sworn in the following week. On 7 May, the bill approving the new government became law after it was given its final approval in Knesset. The new Israeli government, consisting of many Blue and White and Likud coalition members, was sworn in on 17 May 2020. during
2022 Israeli legislative election On 10 July 2022, Gantz and
Gideon Sa'ar agreed to sign a joint faction agreement, under the overall name Blue and White The New Hope. The following month, the alliance was joined by former
IDF Chief of Staff Gadi Eisenkot and former
Yamina MK
Matan Kahana and was renamed
National Unity. Gantz announced on 1 July 2025, following the exits of Eisenkot and Kahana from the alliance, that the name of the party would revert to Blue and White.
