The change means the Human Rights Protection Party, HRPP, and the Faatuatua i le Atua Samoa ua Tasi, Fast, are again tied on 25 seats, with independent candidate Tuala Tevaga Iosefo Ponifasio holding one seat as the potential kingmaker.
The HRPP Leader and caretaker Prime Minister Tuilaepa Sailele Malielegaoi said on TV1 Samoa on Saturday night that they plan to take legal action against Fast, alleging that it had blatantly violated election laws.
Final results not decided
"The final results of the 2021 general election have not been decided," according to the Electoral Commission.
It warned, on social media, that any comments by media or others about the election are purely speculative.
Official counting begins on Monday.
