A draft bill seen by the BBC suggests Myanmar's new government is to create a role similar to prime minister for pro-democracy leader Aung San Suu Kyi.
Her National League for Democracy party won landslide elections last year but she is barred from the presidency.
The new post would be as "Advisor to the State". She already holds several government positions and has said she will rule Myanmar by proxy.
On Wednesday, her choice for presidency, Htin Kyaw, was sworn in.
