Wikipedia editors have voted to ban the use of articles from British tabloid The Daily Mail and its globally popular website as sources, calling them "unreliable", according to a statement.
The vote means the tabloid's use as a reference should be "generally prohibited", it said.
The Wikimedia Foundation, the not-for-profit organisation that runs the Wikipedia website, acknowledged the vote in a statement cited in The Guardian, but said it was up to its unpaid editors.
The guidelines also highlight that special care should be taken when sourcing from state-associated news organisations, including the Chinese press agency Xinhua, North Korea's Korean Central News Agency, and Press TV in Iran.
They warn they may be propaganda organisations, but do not outwardly ban them.
