KUALA LUMPUR—Former Prime Minister Najib Razak was taken to prison after Malaysia’s top court dismissed his final appeal of corruption convictions, capping a yearslong quest by authorities to prosecute him for his role in one of the world’s largest financial scandals.

The ruling by Malaysia’s Federal Court on Tuesday upheld Mr. Najib’s guilty verdicts on seven charges including abuse of power, money laundering and criminal breach of trust. He was convicted in 2020, sentenced to 12 years in prison and fined almost $50 million, but his punishment was stayed throughout the appeals process.
