British Ambassador Dan Chugg has congratulated Aung San Suu Kyi on her victory in Myanmar’s general elections.

“My congratulations to Daw Aung San Suu Kyi and the National League for Democracy on a resounding victory. The high turnout and enthusiasm for the elections highlight what an important milestone this was on Myanmar’s path to democracy,” Mr Chugg said.

“We are encouraged that the NLD has expressed a desire to work with ethnic parties to form a Democratic Federal Union. The UK looks forward to supporting Myanmar’s aspirations for peace and full democracy,” he added.

The ruling NLD party secured an absolute majority in Myanmar's election, official results showed Friday, in a poll disputed by the military-aligned opposition and criticised by rights groups.

The NLD had already declared a landslide victory based on its own tallies, prompting street celebrations by supporters.

But official figures were still being returned five days after the ballot, only the second such polls since the nation emerged from outright military rule in 2011.

Results announced by the election commission Friday showed the NLD had won 346 seats - more than 50 percent of parliament, even taking into account the quarter of seats reserved for the military under the constitution.
