His father was an active member of
Nepali Congress while Agariya also remained in
Nepali Congress till 2008 when he went to
Madheshi Jana Adhikar Forum, Nepal led by Upendra Yadav with the present vice-president of Nepali Congress Bijay Kumar Gachhadar. In 2009, when the party divided into factions, he came to
Madheshi Janadhikar Forum (Loktantrik) led by Bijay Kumar Gachhadar. The party went through a series of mergers in 2017 to form
Nepal Loktantrik Forum and finally joined
Nepali Congress. Argariya was the president of
Madhesh Province committee of
Nepal Loktantrik Forum. Still, he couldn't live long with
Gachhadar after the merger with
Nepali Congress. He joined
FSF-N to contest the election from
Dhanusha-2 to get profit out of the legacy of
second Madhesh Movement. In 2019,
Naya Shakti Party, Nepal and
Federal Socialist Forum, Nepal merger to form
Samajbadi Party, Nepal. He had a dispute with leadership there and he along with some other
HOR members was in contact with
Mahesh Basnet to break the party with 40% HOR members from the SP-N political party. An ordinance was brought for the same. Still, this plan was left unsuccessful after
Rastriya Janta Party, Nepal and
Samajbadi Party, Nepal merged to form
Janta Samajbadi Party, Nepal. After the merger, Argariya sided with
Mahantha Thakur faction in the party at various points in time. On 4 June 2021, joined the
government as
Minister for Culture, Tourism and Civil Aviation. Still, he was removed by the
Supreme Court of Nepal on 22 June 2021 making the tenure just 18 days which is the smallest to date in history. In an interview with Ratopati, he said it was clear that he could even join
Nepali Congress as he holds a past there. This is because of increased dissatisfaction within
Janata Samajbadi Party, the consensus for the party is thought to have highly decreased among the public in
Terai of Nepal. Previously,
FSF-N and
RJP-N unitedly had contested
2017 election with the promise that they would work to fulfil the demand of Terai. Still, none of the promises was fulfilled and now four years have passed with
By-election date fixed. He said, there was no use of Madhesh Based party if they dedicate themself to same leadership against whom they had raised voice to win the election. He said he would leave Mahantha Thakur now after Nepali Congress government would be formed and join as a minister to work for the public. He also yelled that Gachhadar had proposed him to join NC
government led by Deuba in 2017. He was also promised to be made member of HOR from proportional list of
Nepali Congress. == Electoral history ==
