More than 300 pro-Israel activists met their MPs to voice concerns during the Zionist Federation’s annual Parliamentary lobby day.
They expressed their fears over rising extremism on campuses and the existence of a Hamas-related centre in London during sessions with Parliamentarians on Wednesday.
A training session for lobbyists was led by ZF president Eric Moonman and Jacob Vince of Christian Friends of Israel.
Around 100 MPs, including Sir Alan Beith, Louise Ellman, Lee Scott, Theresa Villiers and Luciana Berger, later met constituents for private meetings.
Representatives of the Jewish community included Chief Rabbi Lord Sacks and Jerry Lewis, vice president of the Board of Deputies.
