NTR died due to ill or Insult?

Union Government’s decision to rename Shamshabad Airport domestic terminal after NTR is leading to charges and counter charges between ruling TRS and opposition TDP and Congress. While TDP is supporting the name change, TRS is opposing it saying Telangana donot want any Andhra leader names. 
Congress meanwhile is opposing name change since at present domestic terminal is named after former PM Rajiv Gandhi. Even after Assembly passed resolution opposing name change, sparks are flying on the entire issue. Congress leader V.Hanumantha Rao said naming the domestic terminal after NTR is only for political gains of TDP. 
He said he will write letter to Telangana CM KCR demanding inquiry on the death of NTR and the circumstances which lead to his death. He said truth should comeout whether NTR died due to insult or due to ill health. He said his party will respect him as a legendary film actor and reminded that NTR’s statue was installed in Parliament main hall during UPA regime.
