HANOI, April 26 (Reuters) - The chairman of Vietnam's parliament Vuong Dinh Hue has resigned, state media said on Friday, in a new sign of political turbulence just weeks after the high-profile dismissal of the country's president.

The head of the assembly is among the four "pillars" of the leadership in Vietnam, which officially has no paramount ruler. Hue, 67, had been touted as a possible candidate for the Communist Party secretary position, Vietnam's most powerful job.
