Liberia Football Association (LFA) is to break ranks with Africa and vote against Morocco when the decision on who will host the 2026 World Cup is held next month.
The North Africans are taking on a triple North American bid from Canada, Mexico and the United States.
In a statement, LFA President Musa Bility said the decision came after talks with President and former World Footballer of the Year George Weah and the government of Liberia.
The vote will take place on 13 June.
Bility is a member of the Confederation of African Football’s executive committee.
Morocco, who are bidding to host the World Cup for a fifth time, want to become only the second African nation to stage the finals, after the 2010 finals took place in South Africa.
