Hong Kong's Acting Chief Executive Donald Tsang announced he would seek guidance from Beijing to resolve a dispute over the tenure of Hong Kong's next leader — to be elected July 10 — in a move pro-democracy lawmakers say would undermine the territory's constitution. At issue is whether the successor to Tung Chee-hwa, who resigned in March citing health reasons, should finish the two years left in Tung's term, as democrats insist Hong Kong's Basic Law stipulates, or serve a new five-year term.
