Mitzvah Day founder Laura Marks became the new senior vice-president of the Board of Deputies, after topping the poll in Sunday's election.
Daily Mail City editor Alex Brummer, vice-chairman of the Board's international division came second, with the third vice-presidential place clinched by Jonathan Arkush, senior V-P in the past triennial.
But sitting vice-president Jerry Lewis lost his seat at the top table; the other unsuccessful candidate was family solicitor Denise Lester.
Ms Marks's success was all the more remarkable since she became a deputy only in January. But she has enjoyed an increasingly high profile as the chair of a Jewish Leadership Council's commission to encourage more women into leadership roles.
