A prominent pro-Palestinian campaigner has admitted plainly that purpose of the Boycott, Sanctions and Divestment movement is to hasten the end of a Jewish state in the Middle East and not to find a route to a peaceful resolution of the conflict.

Supporters of a cultural or academic boycott have in the past claimed that the tactic is a way to push for an end to the occupation.

Writing for the Mondoweiss website, Ahmed Moor, a Palestinian-American writer who was born in the Gaza Strip, said: "Ok fine. So BDS does mean the end of the Jewish state."

Mr Moor, who has previously outlined his support of an academic boycott of Israel, made the comment in a piece questioning whether BDS activists should work with liberal Zionists, a group he dismissed as a contradiction in terms.

He wrote: "I view the BDS movement as a long-term project with radically transformative potential. I believe that the ultimate success of the BDS movement will be coincident with the ultimate success of the Palestinian enfranchisement and equal rights movement.

"In other words, BDS is not another step on the way to the final showdown; BDS is The Final Showdown."

In the piece, the Harvard-educated writer suggested that while he did not believe people could be liberal Zionists "because liberal means we're all equal, and Zionist means we're not," an ad hoc partnership with this group would still help the BDS movement "to get things done".

"I'm not dogmatically against co - operating with people whose views I find objectionable," he said. "If it came down to it, I'd be happy to work with the racist up the street to get the city to fix a neighbo u rhood pothole."

In August, Mr Moor and Antony Loewenstein, who together have authored a book on the one-state solution called After Zionism, spoke at the School of Oriental and African Studies in London.
