First term as Chief Minister, 2001-2002
He was sworn in as the 6th Chief Minister of Tamil Nadu in September 2001 when the Chief Minister Jayalalithaa was barred from holding office by the Supreme Court of India.

Political crisis in AIADMK, 2017
After his exit from AIADMK, Panneerselvam and his supporters appealed to the election commission to take action against the party General Secretary VKS and chief minister EPS .He also made a point to them that he needs the two leaf party symbol to contest in RK Nagar election. Also, Edappadi K. Palaniswami and supporters appealed against him, but the election commission rejected both the appeals and allotted two different symbols to each party.

In August 2017, the Edappadi K. Palaniswami and O. Panneerselvam factions merged. He was made Deputy Chief Minister and was also given the finance portfolio.

Leadership Tussle with Edappadi K. Palaniswami, 2022
On 14 June 2022, citing the party's troubles in the polls, AIADMK district secretaries and other senior party members spoke out to shun the “dual leadership” system and came out publicly in favor of strong unitary leader to strengthen the organisation.

Palaniswami supporters pushed for the change in the party's leadership structure by staging a political coup against AIADMK Coordinator Panneerselvam, who had become weak within the party. According to many sources, of the AIADMK's 75 district secretaries, hardly 10 supported him. Of the party's 66 MLAs, only five MLAs were reportedly on Panneerselvam side and less than 20 percent of the party's general council members behind him ahead of crucial general council meeting on 23 June 2022, which was expected to elect the single leadership to the party.

On 30 June 2022, Palaniswami wrote a letter to Panneerselvam asserting the latter ceased to be the party coordinator as the amendments made to the party's bylaw in the 2021 December executive committee meeting were not recognised in the general council meeting held on 23 June.

On 11 July 2022, the Party General Council abolished the dual leadership model and empowered Palaniswami to be the Party Supremo.

Expulsion from AIADMK
On 11 July 2022, Panneerselvam was expelled as Party Treasurer and primary member of the party for "anti-party" activities by the AIADMK General Council. Dindigul Sreenivasan was made Party Treasurer succeeding him. On 17 August, Justice G. Jayachandran of the Madras High Court ruled the expulsion of Panneerselvam and the decisions of the AIADMK General Council as invalid. On 2 September 2022, a division bench of the High Court upheld the decisions of the AIADMK general council meeting held on 11 July 2022 and set aside the previous court order of the single judge in the appeal case of Palaniswami, thus effectively restoring unitary leadership. On 12 September 2022, the Supreme Court dismissed the plea of Panneerselvam challenging the order of Madras High Court to handover the keys to Palaniswami. On 23 February 2023, the Supreme Court of India upheld the decisions of the AIADMK general council meeting held on 11 July 2022, and dismissed the petition of O. Panneerselvam challenging the previous order of the division bench, thus affirming unitary leadership under Edappadi K Palaniswami. On 28 March 2023, The Madras High Court ruled in favor of Edappadi K. Palaniswami and dismissed the petitions of O. Panneerselvam challenging the resolutions passed at the general council meeting held on 11 July 2022. On the same day, AIADMK announced that Edappadi K. Palaniswami was elected as the general secretary through party's general secretary election. On 20 April 2023, The Election Commission of India recognized Edappadi K Palaniswami as the AIADMK party general secretary, acknowledging the amendments to the party constitution and changes to list of office-bearers. On 19 January 2024, the Supreme Court of India refused to stay the August 2023 order of the division bench of Madras High Court which dismissed the petitions of O. Panneerselvam challenging the July 11 general council resolutions that led to the expulsion of O. Panneerselvam and his supporters from the party, saying the interference at this stage will "lead to huge chaos".

Controversy
A report in The Week in December 2017, alleged that Panneerselvam was on the sand mining baron Sekhar Reddy's payroll. Reddy was arrested by the Income Tax Department in March 2017 on money laundering charges. Five pages of the Reddy's Diary suggest alleged payments made to several AIADMK ministers, MLAs, and many others, amounting to more than ₹48 crore. At least five payments in which the word OPS or the name of his secretary Ramesh was written are shown in the contents of the diary.
