Aung San Suu Kyi says the movement towards democracy in Myanmar will be truly genuine only when the Government supports changes to the constitution.
Myanmar , which is also known as Burma, is undergoing a series of economic and political reforms, after decades of military rule.
Suu Kyi's party, the National League for Democracy, secured a small presence in parliament after by-elections in April this year.
But she says the constitution currently bars her from taking the presidency in future elections.
Suu Kyi said on Insight that if Myanmar is to be a genuine democracy and elections in 2015 are to be fair, then necessary amendments will need to be made to the constitution.
