Vietnam Communist party names security minister as president

HANOI, VIETNAM — Vietnam's Communist Party has named police minister To Lam  president, the government said Saturday, and nominated a new head of the parliament in a major leadership reshuffle.  Unprecedentedly for a one-party nation once known for its stable politics, two state presidents and a parliament speaker have stepped down in less than 18 months, all for unspecified "wrongdoing" amid a major antigraft campaign that is unnerving foreign investors because of its chilling effect on bureaucracy.
