The BBC’s Middle East editor breached the broadcaster’s rules on impartiality and accuracy in his coverage of conflict in the region, the corporation’s internal watchdog concluded today.

Jeremy Bowen breached internal guidelines in an article posted on the BBC’s website and in a report on the Radio 4 programme From Our Own Correspondent, the BBC Trust’s editorial standards committee ruled.

In a piece for the website written in 2007 explaining the historical significance of the Six-Day War in 1967, Bowen wrote of Israel's “defiance of everyone’s interpretation of international law except its own”.

Although it rejected the majority of the complaints about inaccuracy, the committee said that with this and other comments the journalist had failed to use the “clear, precise language” needed when covering such a sensitive subject as the Middle East.

Also finding that the article had breached impartiality rules, the trust said that Bowen had failed to acknowledge that there were views contrary to his own.

The committee said: “Readers might come away from the article thinking that the interpretation offered was the only sensible view of the war.”

In Bowen’s report for From Our Own Correspondent, on January 12 last year, he said that the US Government considered Har Homa, an Israeli settlement south of Jerusalem, to be illegal.

The committee, however, said that claim breached accuracy rules because Bowen had failed to acknowledge that the information came from his own “authoritative source”, rather than official channels. It dismissed other complaints about accuracy and impartiality.

BBC journalists are subjected to some of the fiercest scrutiny of any media organisation in the world, and the corporation regularly receives complaints about its coverage of the Middle East, from both sides.

In January the corporation was attacked by supporters of the Palestinian cause after it refused to screen an appeal made by the Disasters Emergency Committee for aid to Gaza, citing impartiality concerns.

In 2006 The Thomas Report, an external examination of the corporation’s coverage of the conflict, found that there was no systematic or deliberate bias.

The BBC is currently engaged in a High Court battle to try to stop the release of a similar internal document, The Balen Report, written in 2004 to examine the corporation’s coverage.
