Governor E.S.L. Narasimhan administered the oath of office and secrecy to the TRS leader at 1.25 a.m. at a ceremony held at Raj Bhavan.

Mohammed Mahmood Ali, a member of Telangana Legislative Council, also took oath as a Minister. Ali, who was Deputy Chief Minister in the previous cabinet, is likely to retain the same post.

KCR, as Rao is popularly known, took oath in Telugu while Ali completed the formalities in Urdu.

TRS leaders in the audience raised slogans of "Long live KCR" and "Jai Telangana" as the 64-year-old finished taking the oath.

KCR is likely to expand his cabinet next week. The TRS retained power by winning 88 seats in the 119-member Assembly.

KCR's wife Shobha Rao, son K T Rama Rao, daughter K Kavitha, nephew T. Harish Rao and other family members attended the ceremony.

After the swearing-in, a group of priests blessed KCR and presented him 'prasadam'.

KCR had taken oath as Telangana's first Chief Minister on June 2, 2014, the day when Telangana came into being as India's 29th state.

He went for a dissolution of the Assembly on September 6 this year, eight months before its term was to end. His gamble for early polls paid rich dividends.

Newly elected legislators of TRS, top party leaders, All India Majlis-e-Ittehadul Muslimeen (AIMIM) President Asaduddin Owaisi, Chief Secretary S.K. Joshi, Director General of Police Mahender Reddy and senior officials attended the.
