The BBC has upheld a complaint that Jeremy Paxman failed to challenge adequately the Labour MP, Louise Ellman, after she accused Hamas of using children as suicide bombers.
Andy Bell, complaints director of the BBC's Editorial Complaints Unit, apologised for a "lapse in editorial standards" in the BBC2 airing of Newsnight on February 14.
During the programme, Mr Paxman interviewed Mrs Ellman, MP for Liverpool Riverside, and the children's writer, Michael Morpurgo, about Mr Morpurgo's documentary on the children of Israel and Gaza.
Mrs Ellman said: "The problem is Hamas, who use these children as human shields, who give the children explosives, or sometimes force them to have explosive belts, and send them to blow up Israeli civilians."
