CORRECTION: At timecode 25:16 of this programme, the phrase "range of shareholders" appears with respect to We Believe in Israel and who it works with. The correct wording is "range of stakeholders." In the first of a four-part series, Al Jazeera goes undercover inside the Israel Lobby in Britain. We expose a campaign to infiltrate and influence youth groups, including the National Union of Students, whose president faces a smear campaign coordinated by her own deputy and supported by the Israel Embassy.
