The BBC has apologised and agreed to pay damages to Ukraine's President Petro Poroshenko.
The apology relates to an incorrect report claiming a payment was made to extend a meeting between Mr Poroshenko and US President Donald Trump.
An article, published last May but since removed from the BBC website, alleged $400,000 was paid to Mr Trump's former lawyer Michael Cohen.
The allegation, relating to a meeting in June 2017, was untrue.
The BBC also featured the report in a News at Ten television bulletin in the UK.
"We apologise to Mr Poroshenko for any distress caused and have agreed to pay him damages, legal costs and have participated in a joint statement in open court," the broadcaster said.
