T. Rajaiah was born on 12 July 1965 in Warangal in a madiga community and later converted to Christianity.
T. Rajaiah won over Kadiyam Srihari in Andhra Pradesh State Assembly Elections 2009 for INC in Station Ghanpur Assembly Constituency. He joined the Telangana Rashtra Samithi party on 30 October 2011 revolting for Telangana state. He won in by-election in 2012 representing the TRS party.He served as the Deputy Chief Minister & Minister for the Department of Health and Family Welfare Govt. of Telangana in the Cabinet of Ministers of Sri K Chandra Sekhar rao (KCR)led Government in Telangana with effect from the Telangana State Formation Day, 2 June 2014.
Charges of corruption in the Telangana's medical and health department surfaced and indicated Madiga Deputy Chief Minister Thaikonda Rajaiah's involvement or 'tacit ignorance' of illegal actions in the department. While Rajaiah's dismissal appeared to have been on the cards for quite a time since September, 2014 when he promised a Health University for Warangal seemingly without Telangana CM Kalvakuntla Chandrashekar's direction.
Chief minister's political secretary S Subhash Reddy said, "The developments were on expected lines. The matter of corruption charges against a minister is a serious one."
Rajaiah has earned the dubious distinction of being the First Minister in Telangana to be sacked. Allegations of corruption against the health and medical department include irregularities in recruitment of para-medical staff and purchase of ambulance vehicles.
In a last ditch effort to defend himself, Rajaiah had written to the chief minister seeking forgiveness for his omissions and commissions, but to no avail.
On Jan 25, 2015, before Republic Day, Rajaiah was "supposedly" sacked for his behavior. His duties were transferred to a Bindla caste member (non-madiga) member Kadiyam Srihari who is also from Warangal, in order not to lose the Scheduled Caste vote bank. Mr. Srihari was considered the hidden hand behind the Madiga movement for categorisation of Scheduled Castes though he belonged to the Baindla community which is considered lower in strata than Madigas.
Speaking to scribes after spending one night at Manchiryal area hospital as a part of his visit to Adilabad district said there is nothing wrong in hospital staff demanding Rs 100 and Rs 200.
He said one shouldn't look at them as corrupt people and one shouldn't complain calling the authorities. He said only if someone pesters patients, people can complain them to RDO or Collectors calling them over phone. Rajaiah even changed his statements on swine flu deaths. Rajaiah who said five people were killed due to swine flu till yesterday now said there are no deaths due to swine flu.
During an event in Warangal, Thatikonda Rajaiah promised a Health University for Warangal seemingly without Telangana CM Kalvakuntla Chandrashekar's direction. Speaking in the same event, CM KCR had rebuked Thatikonda Rajaiah by saying, "ollu daggara pettukuni matladu", which did not go well among the Madiga caste members including Manda Krishna Madiga leader of the vetti-chakiri oppressed section of the Telangana. It was aired that KCR did not want any of his ministers to make promises, since he wants to take credit for all the schemes and programmes.
In his complaint, Bakka Judson, TPCC secretary, objected KCR's use of 'ollu daggara pettukuni matladu', loosely translated as 'mind your language' by KCR claiming that it insulted Dr T Rajaiah, a Dalit Christian.
"Deputy chief minister Dr T Rajaiah belongs to SC (madiga) caste. The remark made by CM K Chandrasekhar Rao was in bad taste," Bakka Judson said in his complaint before National Commission for SC.
Madiga Reservation Porata Samiti (MRPS) founder president Manda Krishna on Monday lashed out at Telangana Chief Minister K. Chandrasekhar Rao for sacking Deputy Chief Minister T. Rajaiah and said it amounted to insulting the community on the whole. While not exactly spelling out his future course of action, the MRPS leader said he would chalk out an action plan on the ouster of Dr. Rajaiah soon but reiterated that the ‘Madigas’ would not rest until justice was done. He regretted that Dr. Rajaiah was not even given an opportunity to explain his position. “The way he was denied even an appointment with the Chief Minister and removed solely on the basis of an allegation is mysterious and that is what is insulting,” he said.
The fight of the weaker sections has always been for self-esteem alone and the way Dr. Rajaiah was unceremoniously shown the door only holds mirror to the continued oppression of the weaker sections by upper castes, he said, adding that they would take the struggle forward. The Chief Minister owed people an explanation of how and under what circumstances Dr. Rajaiah was removed and the demand for an apology for such a treatment was justified, Mr. Krishna said.
Rajaiah suffered Heart Attack and was admitted in Hyderguda Apollo Hospital, Hyderabad on 27-01-2015. The former Deputy Chief Minister who was sacked by Telangana ChiefMinister K. Chandrasekhar Rao on Sunday on the charges of corruption in the Health Department, was hospitalized on Tuesday evening after complaining pain in the chest.
