Rihards Eigims, head of Our Party, on August 23 said that he had lost confidence in the current mayor and that Our Party will leave the coalition and instead cooperate with the Latgale Party of former long-standing Daugavpils mayor Jānis Lāčplēsis.
Unusually, Eigims announced the move in a press conference held in the Russian language.
The shift of power means Andrejs Elksniņš, a former Harmony MP, could be ousted from the mayor's seat he acquired after the June 8 municipal election.
Jānis Lāčplēsis said the Latgale Party is "ready to discuss any candidate", perhaps suggesting that Eigims will become the new mayor as Lāčplēsis has not announced his candidacy.
Eigims' and Lāčplēsis' parties hold ten seats at the fifteen-seat Daugavpils City Council.
Meanwhile Andrejs Elksniņš told Latvian Radio he intends to continue in his post as normal.
