How much do we really know about Zionist influence on British elites?

The entire Channel 4 Dispatches investigation of the Zionist lobby’s influence on British politics.

This Guardian piece sums up the desperate need to fully uncover the role of Likud extremism on the democratic system:

Every year a very grand lunch is given by the Conservative Friends of Israel at a central London hotel. Anyone who is anyone in the Conservative party makes it their business to be there. It is normally addressed by the party leader.

This year’s event took place in June, with the main speech by David Cameron, and the shadow foreign secretary, William Hague, in attendance. The dominant event of the previous 12 months had been the Israeli invasion of Gaza. We were shocked Cameron made no reference in his speech to the massive destruction it caused, or the 1,370 deaths that resulted, or for that matter the invasion itself. Indeed, our likely future prime minister went out of his way to praise Israel because it “strives to protect innocent life”. This remark was not intended satirically.

Afterwards, we resolved to ask the question: what are the rules of British political behaviour that cause the Tory leader,his mass of MPs and parliamentary candidates to flock to the Friends of Israel lunch in the year of the Gaza invasion? And what are the rules of media discourse that ensure such an event passes without even being noticed?
