Chennai: Tamil Nadu Chief Minister J Jayalalithaa on Friday filed her nomination papers for the upcoming bypolls from RK Nagar Assembly seat in Chennai.

This is the first time that Jayalalithaa would be contesting from a constituency, which was considered to be a DMK bastion.

Having been acquitted in a wealth case that threatened to derail her political career, Jayalalithaa returned as Chief Minister of the state for the fifth time last month and has to be elected as MLA within six months.

P Vetrivel of AIADMK had quit as MLA of RK Nagar on May 17, paving the way for Jayalalithaa to contest from a city constituency and return to the 234-member state Assembly in which her party enjoys a strong majority of 150.

While DMK, MDMK, VCK and PMK have announced boycotting the bypoll, CPI with the support of CPI(M) has decided to contest while NDA constituents BJP and DMDK are yet to make up their mind.
