A memo written by the BBC’s world news editor, Jon Williams, and sent to fellow executives, says the cost of reporting the rescue will exceed £100,000.
It will also result in cuts to coverage of the Cancún climate summit, which begins in November, the Nato summit in Lisbon, and the Davos World Economic Forum.
BBC News has sent 26 people to cover the dramatic rescue of the San José miners, pushing its annual budget far beyond its agreed limit.
“The financial situation is serious”, Williams warns. “We are currently £67k beyond our agreed overspend of £500k; newsgathering’s costs for Chile will exceed £100,000.”
