In December 2011, there was speculation that Aung San Suu Kyi would run in the 2012 national by-elections to fill vacant seats. On 18 January 2012, Aung San Suu Kyi formally registered to contest a Pyithu Hluttaw (lower house) seat in the Kawhmu Township constituency in special parliamentary elections to be held on 1 April 2012. The seat was previously held by Soe Tint, who vacated it after being appointed Construction Deputy Minister, in the 2010 election. She ran against Union Solidarity and Development Party candidate Soe Min, a retired army physician and native of Twante Township.
