High Quality Content by WIKIPEDIA articles! Thambirajah Tharmadurai (born 1948), better known as T. T. Durai, is the former Chief Executive Officer of the National Kidney Foundation Singapore (NKF). He is the central figure in the National Kidney Foundation Singapore scandal and is currently on bail facing corruption charges. Durai was once highly respected as the head of an extremely successful fundraising organisation. But in July 2005, Durai resigned amid controversy following the collapse of a defamation trial which the NKF brought against Singapore Press Holdings (SPH). Various revelations emerged during the trial about spending from the charity's funds on luxury items which appeared to be for the personal use of Durai and his wife.
