Myanmar president says by-elections "very successful"

PHNOM PENH (Reuters) - Myanmar President Thein Sein said on Tuesday that landmark weekend by-elections swept by Aung San Suu Kyi's party were carried out successfully, signalling acceptance of a result that will boost the political clout of his party's biggest rival.

"It was conducted in a very successful way," the retired general told reporters during a summit of Association of South East Asian Nation leaders in Cambodia, his first public comment on Sunday's elections for vacant parliamentary seats.
