Malaysian former prime minister Najib Razak, fighting dozens of charges over a multi-billion-dollar graft scandal at state fund 1MDB, faces his first verdict on Tuesday in a landmark case that tests the country's efforts to stamp out corruption and could have big political implications.

Najib was voted out in a historic 2018 election amid public anger over allegations that $4.5 billion was stolen in a globe-spanning scheme from 1Malaysia Development Berhad (1MDB), a fund he co-founded. Prosecutors allege more than $1 billion made its way into his personal accounts.

His party returned to power this year in an alliance led by Prime Minister Muhyiddin Yassin, prompting some to question how whether the return would affect several corruption cases against Najib and his allies.
