Lata Thakur was a Scheduled Tribe candidate and won the 1972 MLA seat from Lahaul and Spiti against
Thakur Devi Singh of the
Lok Raj Party. At Lata Thakur's request, Prime Minister
Indira Gandhi visited the
Lahaul and
Spiti valleys in June 1972. Gandhi again visited Spiti in June 1974, though this time only to Sumdo, near the Indo-Tibetan frontier. This visit nonetheless further bolstered Congress's and Lata Thakur's position there. Lata Thakur brought about the provision of supplying fuelwood at subsidized rates and without transportation charges to all locals of the remote Spiti valley for the winter. Alongside, Lata Thakur served as the president of the Himachal Pradesh Youth Congress Committee. As Youth Congress convener, she contended that the youth should be involved in the drawing of development projects. She also served as the president of the Himalayan Buddhist Society at
Manali. Lata Thakur and
Vidya Stokes were critical of
Yashwant Singh Parmar's book
Polyandry in the Himalayas, claiming that the book could have a negative effect on the women of the state, and that Parmar did not understand Himachali women well. Around the time of the inauguration of the
Atal Tunnel in October 2020, there were claims that Lata Thakur had been instrumental in initiating the idea of building a tunnel under the
Rohtang Pass, so as to provide the Lahaul valley with round-the-year road connectivity. The claims were that she had talked to Indira Gandhi of this need on one of the PM's visits to the
Lahaul and Spiti district during Lata's tenure as MLA, and that the chain of events set-off by this discussion had materialised several decades later in the form of the
Atal Tunnel. == Personal life ==
