Political milestones in the 1970s  

In Government

In 1969, Peres was appointed Minister of Absorption and in 1970 he became the Minister of Transportation and Communications. In 1974, after a period as Information Minister, he was appointed Minister of Defense in the Yitzhak Rabin government having been Rabin's chief rival for the post of Prime Minister after Golda Meir resigned in the aftermath of the Yom Kippur War. During this time, Peres continued to challenge Rabin for the chairmanship of the party, but in 1977, he again lost to Rabin in the party elections.

First time acting as Prime Minister

Peres suceeded Rabin as party leader prior to the 1977 elections when Rabin stepped down in the wake of a foreign currency scandal involving his wife. As Rabin could not legally resign from the transition government, he officially remained Prime Minister, while Peres became the unofficial acting Prime Minister. Peres led the Alignment to its first ever electoral defeat, when the Likud Party under Menachem Begin won sufficient seats to form a coalition that excluded the left. After only a month on top, Peres assumed the role of opposition leader.
