The British Prime Minister's Director of Communications, Alastair Campbell, has acknowledged that the British government made a mistake in compiling a dossier on Iraq, and has apologised.
He was appearing before a committee of Westminster MPs who are investigating whether or not information was manipulated in order to exaggerate Tony Blair's case to go to war against Iraq.
Mr Campbell told the committee that during the process of drafting the document, published in February this year, there had been a failure to properly attribute research work by an American student.
Mr Campbell insisted he was initially in the dark about the error.
But he denied twisting the intelligence evidence on weapons of mass destruction in Iraq.
