Hue's resignation takes place four days after his assistant Pham Thai Ha was arrested on charges of abusing his position and power for personal gain, according to state media.

Vietnam's Communist Party accepted what called Hue's voluntary resignation, according to VN Express, while noting that investigators found that Hue had “violated Party regulations, and his violations have affected the reputation of the Party, the State and himself.”

Hue, 67, had been the chairman of Vietnam's national assembly for over three years. The chairman of the national assembly is the fourth most important politician in Vietnam, along with the President, the Prime Minister and the head of the Communist Party.

Former President Vo Van Thuong resigned in late March in similar circumstances.
