A video clip showing the caretaker premier allegedly smiling shortly after she appeared to be on the brink of tears during a press conference has gone viral. Ms Yingluck told the press conference that she will not step down as caretaker premier until a new cabinet has been formed after the general election scheduled for Feb 2.
She was visibly emotional when she answered a question about anti-government protesters' calls to evict the Shinawatra family from Thailand at the Thai Army Club press conference on Tuesday morning.
"We are fellow Thais. Why do we have to hurt one another?
"I have retreated so far and I don't know where to retreat further.
"Do you (anti-government protesters) want me to not even set foot on Thai soil?" Ms Yingluck said in a trembling voice.
But reports alleged that Ms Yingluck turned and smiled to a reporter who called out to her as she left the podium.
Members of social networks have been sharing a video clip which appears to show Ms Yingluck turning around and smiling at someone around 10 seconds after delivering her teary-eyed speech to the media.
The video sparked various theories on whether Ms Yingluck had faked her emotional response to reporters before being unknowingly caught on camera smiling shortly after.
A Youtube user named Nuttapol Kittiwarawut commented on the video clip saying: "Wow! Such an actress!"
However, Ms Yingluck's supporters said she was only smiling to try and hide her true feelings and maintain her dignity as a leader.
A Youtube member using the alias Michael Lee argued Ms Yingluck was just trying to smile to alleviate the pressure she is under.
A Pantip user called Minning said: "Her smile meant she is OK, although she cried and was tired. Those wanting to destroy the PM with this nonsense are retarded."
The video clip, uploaded to YouTube by a user called Gun Rose, shows the prime minister smiling after her emotional appearance on national television. The clip had drawn more than 342,000 hits just hours after being posted.
