Suu Kyi and her National League for Democracy (NLD) have kept a tight lid on who they want to become the president of Myanmar's first popularly elected government in decades, as they navigated the tense four-month political transition since November's landmark elections.
But with just days to go before they are set to announce their preferences on Thursday, and with Suu Kyi still blocked from the role by the junta-era constitution, a letter purporting to reveal the selecting emerged on social media yesterday.
The purported document, which was stamped with an official NLD logo, listed current presidential favourite Htin Kyaw and ethnic Shan MP Hkun Tun Oo as the party's nominees for the roles of vice presidents -- one of whom would be selected as leader.
Suu Kyi, 70, has vowed to rule "above" whoever the next president is, meaning that the role would have to go to someone whose absolute loyalty was assured.
