Wisconsin's election commission said on Friday it had received petitions for a recount of votes in the presidential election from the Green Party campaign and another candidate and was planning to start the process.

The recount process, including an examination by hand of the nearly 3 million ballots tabulated in Wisconsin, is expected to begin late next week after Green Party candidate Jill Stein's campaign has paid the required fee, the Elections Commission said.

"The Commission is preparing to move forward with a statewide recount of votes for President of the United States, as requested by these candidates," Commission Administrator Michael Haas said in a statement.

The move follows comments by Jill Stein, Green Party presidential candidate, earlier on Friday that her push for election recounts in Wisconsin, Michigan and Pennsylvania was aimed at assessing the integrity of the US voting system, not at undermining Republican Donald Trump's White House victory.

Victories in Wisconsin, Michigan and Pennsylvania for Democratic candidate Hillary Clinton would have won her enough electoral votes to win the election.

While Ms Stein's effort this week may have spurred hope among disappointed supporters of Mrs Clinton, the chances of such recounts overturning the overall result from the November 8 election are extremely slim, given Mr Trump's margins of victory in the three states.
