Transport Minister Anthony Loke has resigned from the cabinet effective immediately as jailed former prime minister Najib Abdul Razak heads home to serve the remainder of his jail sentence.

The DAP secretary-general said his resignation is a matter of principle, as he previously announced that his last day as transport minister would be when Najib begins his house arrest, and he was sticking to his stance on the matter.

"Following today's Kuala Lumpur High Court decision allowing Najib to serve his sentence under house arrest, and in line with the position I announced last Friday, my resignation as transport minister takes effect immediately," Loke said in a statement today.

He also thanked Prime Minister Anwar Ibrahim for the trust given to him since December 2022.
