To Lam, who already served as Vietnam’s president, has been confirmed as the general secretary of the Communist Party. The former security officer vowed to continue a sweeping crackdown on corruption.

Vietnamese President To Lam was named general secretary of the Communist Party on Saturday.

The position is the country’s most powerful political role.

Communist Party delegates unanimously supported Lam’s nomination, officials said.

Lam replaces Vietnam’s longtime leader Nguyen Phu Trong, who died two weeks ago. It remained unclear whether Lam would also stay on as president.
