KUALA LUMPUR—Malaysia’s Anwar Ibrahim was sworn in as prime minister on Thursday, capping a three-decade political journey from a protege of veteran leader Mahathir Mohamad to protest leader, a prisoner convicted of sodomy and opposition leader.
His appointment ends five days of unprecedented post-election crisis, but could usher in a new instability with his rival, former prime minister Muhyiddin Yassin, challenging him to prove his majority in parliament.
