The Uthangarai (Reserve) constituency came into being after a gap of 35 years following the delimitation process undertaken by the Election Commission of India just before the 2009 Parliamentary elections.
Prior to this, parts of Uthangarai constituency were attached to the Harur (Reserve) constituency. T.T. Gounder of Indian National Congress party won from this segment in 1967 Assembly elections. He had defeated DMK candidate K.R. Krishnan by a margin of 2,040 votes.
K.R.K. Narasimhan, son of Mr. Krishnan, was elected in the Bargur by-election immediately after the 2009 Parliamentary elections.
For this Assembly elections, Viduthalai Chiruthaigal Katchi is fielding Muniammal Kaniamuthan (35), wife of Mr. Kaniamuthan, State Deputy Secretary of Traders Wing.
AIADMK candidate Manoranjitham Nagarajan (36) is holding the post of District Deputy Secretary in the party. She was elected as president of Krishnagiri Panchayat Union between 1991 and 1996.
The constituency depends on the perennial South Pennar River and Pampar River for its drinking and irrigation needs. Due to poor maintenance of the canal from Benugondapuram lake, the Pampar Dam remains dry. Construction of a dam in Andiyur in Vellore district across South Pennar River is said to be the reason.
Though there are eight lakes which irrigate over 3,000 acres, most of the time, the lakes remain dry due to poor maintenance of the canals in the catchment areas. Farmers prefer cultivation of fruits such as sappota, guava, and horticulture products in this region. Farmers undertaking horticulture want a direct procurement centre here to get maximum price for their produce.
The constituency is surrounded by Dharmapuri, Vellore and Tiruvannamalai districts. There is no major industry in the area. The lone spinning mill, Uthangarai Cooperative Spinning Mill, is in red due to poor governance for the last several years.
The other main issue here is the badly maintained National Highway No. 66 which connects Krishnagiri and Tindivanam. The Centre approved the two-laning project at Rs. 610.21 crore in November last.
The total number of voters in this constituency is 1,86,855 (men 95,259, women 91,570, defence personnel 24, transgenders 2). The areas comes under the constituency is the entire Uthangarai taluk and part of the Pochampalli taluk.
