Aung San Suu Kyi says she will stand for election to parliament as her party rejoins the political process in Myanmar.
The National League for Democracy said on Friday it would register to run in as yet unscheduled by-elections.
The party boycotted the last polls in November 2010, the first in 20 years, because of election laws that banned Ms Suu Kyi - a former political prisoner - from running. This regulation has since been dropped.
The NLD previously won elections in 1990, but was never allowed to take power. Ms Suu Kyi spent years under house arrest but was freed a year ago by the new government.
Since then it has entered into dialogue with her and freed some political prisoners.
