Because I am Jewish

From Jamie Susskind's letter of resignation from the Labour Party:

I am resigning my membership because I can no longer belong, in good faith, to an institution that has allowed itself to become the foremost platform for anti-Semitism in British public life. Holocaust deniers and racists have been emboldened by the silence (and in some cases complicity) of senior figures in the party. In part, therefore, I am leaving Labour for the same reason that I joined: because I am Jewish.
