The explanation Abrahams makes does not make much sense to me. "Giving in secret" (Matan b'Seter) is recommended in cases of charity. When one donates to a political party, it is usually done for reasons that involve at least some self interest. And if only one or two people are aware of the secret giver, what benefit is it to him unless those one or two have some authority to engage in "compensation"? Let the British police follow up on this scheme. The Jewish community can survive an occasional crook, or else they are in big trouble, which the British Jewish community does not seem to be in.
