It is hard to tell who comes out worse from the Kaminski row. The Conservatives have shown a worrying lack of sophistication in their failure to anticipate the reaction of the Jewish community to their alliance. The Board of Deputies, in particular its president, Vivian Wineman, showed naïveté by sending its letter, drafted nearly a month ago, to David Cameron in the middle of Conservative Party Conference. There are also claims that Mr Wineman did not consult with the professionals available to advise him. As for the Jewish Leadership Council, it is unclear why its members are involved in nitty-gritty political work when they supposedly belong to a body setting broad strategy. And their contemptuous remarks about Mr Wineman – who is also their own chairman – also raises question marks about their attitude to the community they lead. Mr Wineman is, after all, the only one of them to have any kind of democratic mandate, having been elected by deputies from throughout the country. The lesson from this saga is clear: Our leaders, self-appointed and otherwise, must stop squabbling and start communicating.
