解説 クロアチア大統領選挙(2025年1月12日)

2025年1月12日、クロアチアで実施された大統領選挙の決選投票において、野党の社会民主党(SDP、中道左派)が支援する現職のゾラン・ミラノビッチ大統領が再選を果たした。同大統領は、全郡および首都ザグレブにて与党推薦の対立候補であるドラガン・プリモラツ元教育・科学相を破り、約75%の票を獲得して、クロアチアの大統領選挙史上最大の得票率差で勝利を収めた。圧勝の理由としては、アンドレイ・プレンコビッチ首相率いる与党・クロアチア民主同盟(HDZ、中道右派)への汚職スキャンダルなどの不満が広がる中で、与党にすべての権限を集中させたくないという有権者の意向が働いたことに加えて、ミラノヴィッチ大統領の主権主義的な政策が中道左派系支持者のみならず、中道右派や右派の有権者からの支持にもつながったことなどがあげられている。

ミラノビッチ大統領は、外務省出身で、大統領就任以前は社会民主党に所属していた。2011年から2016年までクロアチア首相を務め、EU加盟を実現させた立役者である一方で、ウクライナへの軍事支援やウクライナのEU加盟に対して否定的な姿勢を示していることでも知られている。大統領は軍の最高司令官を務めるが、2000年の憲法改正以降の権限は外交安全保障分野での発言権に限定され、法案拒否権や実質的な議会解散権を持たない儀礼的な役職とされている。クロアチア政治の実権を握るプレンコビッチ首相はウクライナ支援に賛成していることから、今回の選挙がクロアチア外交に及ぼす影響は小さいと考えられるものの、再選を果たしたミラノビッチ大統領との外交政策をめぐる緊張関係は今後も続くことが予想される。(石川雄介)
