She was likely to address two public meetings, one in Chenni City, and the other, most probably, in a southern district on April 5 for the DMK-led Front.
Apart from DMK President and Tamil Nadu Chief Minister M Karunanidhi, leaders of alliance partners, including the PMK, VCK and the IUML, were expected to attend the public meeting in Chennai.
She would visit Puducherry the next day to address an election meeting.
The sources said a detailed programme of her visit would be announced later.
Tamil Nadu and Puducherry will go to the polls on April 13.
