[2] Natrah made her electoral debut in the Johor state assembly elections in 2013 in a losing effort to UMNO’s Ayub Rahmat by 2,260 votes in the Kemelah constituency.
Five years later in 2018, she won a rematch against Ayub, this time defeating him by 1,281 votes to win the Sekijang parliamentary seat.
Natrah was one of the first-time MPs elected as the Pakatan Harapan coalition swept into power, ending the 61 years rule of the BN federal government.
In 2021, Natrah claimed she had been approached to defect and give her support as a federal lawmaker to the Perikatan Nasional government led by the then-Prime Minister Muhyiddin Yassin.
However, in the 2022 general election, she was not fielded as a PKR candidate due to her ailing heath, with Dr Zaliha Mustafa succeeding her as the Sekijang MP.
