The initiative for the unique vote was taken by a civil movement with the support of the ruling Democratic Progressive Party (DPP). The members from Kuomingtang, which make up a fifth of the parliament, have been accused of being in China's lead.
The election result could have changed the balance of power in Taiwan. A deadlock has prevailed in politics for several months between the DPP government and the parliament where Kuomingtang and its allies have a majority.
The official result of the vote will be announced on August 1 by the country's election committee. If the preliminary result stands, it means that President Lai Ching-Te will also in the future face strong opposition from the parliament.
The leader of Kuomingtang, Eric Chu, believes that the voters have used their right to vote to prove that Taiwan's democracy is mature and functioning.
Taiwan's population chose stability and that the government should focus on getting things done, rather than engaging in bitter political struggles, he says.
