Chennai: Tamil Nadu's ruling All India Anna Dravida Munnetra Kazhagam (AIADMK) has entered into an electoral pact with actor-politician Vijayakanth's Desiya Murpokku Dravida Kazhagam (DMDK). The DMDK will contest four Lok Sabha constituencies in the state, deputy chief minister and party coordinator O Panneerselvam confirmed on Sunday.

During the announcement of the alliance, Panneerselvam said that the DMDK would also support the AIADMK in the by-elections for 21 Assembly constituencies.

He said though the Election Commission has announced by-elections only for 18 assembly constituencies along with the Lok Sabha polls, the DMDK will support the AIADMK whenever the by-polls are held for the remaining three seats.

Panneerselvam said the constituency allocation to allies would take place after interactive discussions.

The DMDK treasurer Premalatha said the alliance would continue even for the local body elections in Tamil Nadu.

The Election Commission on Sunday announced that the Lok Sabha elections would begin on April 11 and polling would be held over seven phases through May 19, followed by counting of all votes on May 23.

Tamil Nadu will fall under phase two where 39 constituencies will go to polls on April 18. Along with Tamil Nadu, Puducherry's sole constituency election will be held on April 18. Karnataka's 14 constituencies will also go to polls on April 18.
