Prime Minister Shinzo Abe plans to reappoint all of his Cabinet ministers next week in light of the ruling coalition's big win in the snap election last week, a senior lawmaker said.

Abe will also leave the leadership of his conservative Liberal Democratic Party unchanged, LDP General Council Chairman Wataru Takeshita said during a speech Friday in Toyama Prefecture.

Takeshita quoted Abe as telling a meeting of party executives on Monday that "it is natural for everyone to be retained." The current lineup was appointed after a scandal-induced reshuffle in August.

The LDP won 284 of the 465 seats in the Lower House election, which allowed it to maintain its two-thirds majority with Komeito, its smaller partner in the ruling coalition.

Abe is set to be voted back in as prime minister on Wednesday during a special Diet session.
