Unverifiable: India was probably the first country to re-elect the party which introduced Goods and Service Tax.

The Election Commission of India data shows that the BJP was elected first in 2014 and then again in 2019.The Union Government led by the Bharatiya Janata Party(BJP) passed the Goods and Services Tax(GST) in both the houses of the Parliament, Rajya Sabha and Lok Sabha, on 3 August 2016 and 8 August 2016 respectively. The BJP had first come to power in 2014 and was re-elected in 2019 general elections. The Australian Government led by the Liberal Party under the leadership of John Howard passed the GST bill in the year 2000, which can be verified by the Journal of Australian Taxation. Still, the party lost the elections in 2007, which is confirmed by the National Archives of Australia. GST was introduced in NewZealand by the Labour Party in 1986, which is confirmed by the New Zealand History website. The report published by Revolvy shows that the Government lost the mandate in the year 1990. India did vote in favour of the BJP government after it introduced Goods and Services Tax, but whether India was the first country to do so is unverifiable.
