2006–07_Tamil_Nadu_Legislative_Assembly_by-elections
By-elections to two state assembly constituencies were held in Tamil Nadu, India, in two separate phases. Election for Madurai Central was held on 11 October 2006 and for Madurai West was held on 26 June 2007. The election results were not expected to change the prospects of the party in power, the Dravida Munnetra Kazhagam (DMK), and its Chief Minister M. Karunanidhi.
Both phases of this by-election resulted in a big victory for DMK and Indian National Congress, who were part of the Democratic Progressive Alliance. Even though in 2006 assembly elections, AIADMK and its allies got more votes than DPA, when all the constituencies in Madurai are taken into account, the victory in both Madurai constituencies shows the increase in support by the people of Madurai for the DMK government and its policies since 2006.
