KUALA LUMPUR,– Former interior minister Muhyiddin Yassin was named as Malaysia’s new prime minister Saturday, royal officials said, signalling the end of Mahathir Mohamad’s rule and return to power of a scandal-plagued party.

Muhyiddin will be sworn in Sunday, the palace said, ending a week of turmoil after the collapse of the reformist government and Mahathir’s resignation as premier.
