In 1877 David Lindo Alexander became representative on the Board of Deputies of British Jews for the Ashkenazi Central Synagogue in Great Portland Street, rising to become president of the organization between 1903 and 1917.
[5] Alexander is remembered as co-signatory, along with Claude Montefiore, president of the Anglo-Jewish Association, of a letter to The Times on 24 May 1917, which declared "grave objections" to two claims in the "published statements of the Zionist leaders": "The first is a claim that the Jewish settlements in Palestine shall be recognized as possessing a national character in the political sense... the second... is the proposal to invest the Jewish settlers in Palestine with certain special rights in excess of those enjoyed by the rest of the population".
On behalf of the Association and the Board of Deputies the two presidents rejected what they saw as the conflation of nationality and religion: Emanicipated Jews in this country regard themselves primarily as a religious community...
On 28 May The Times published critical responses from Lord Rothschild, the Chief Rabbi, Joseph H. Hertz and from Chaim Weizmann, president of the British Zionist Federation.
As a result of the vote Alexander was forced to resign and he subsequently co-founded the anti-Zionist League of British Jews, an organization dedicated to resisting the allegation that Jewish people constituted a separate political entity.
