Myanmar President Thein Sein has congratulated Aung San Suu Kyi`s opposition party on its success in polls.With about 40% of seats declared, the National League for Democracy (NLD) has taken nearly 90% of the vote.Ms Suu Kyi has written to the leadership requesting talks on national reconciliation, reports BBC.But spokesman U Ye Htut said such a meeting could only take place after the final results were announced.He insisted there was no attempt to delay the declaration of results from Sunday`s election.Correspondents say Ms Suu Kyi is treading carefully despite her apparent landslide victory. The NLD won elections decisively in 1990 - only for the result to be nullified and Ms Suu Kyi placed under long-term house arrest.The ruling military-backed Union Solidarity Development Party (USDP) - which won the last, widely criticised election five years ago - has won only about 5% of the seats being contested.A quarter of seats are reserved for the military.
