Special pleading?

Ah yes, that letter.  The Guardian has the story:

...  the letter we now know Cameron wrote to the president of the European council in November 2013, warning him against transparency moves on offshore trusts, its neat fit with the Cameron family’s complicated finances, and the extent to which, as he now confesses, the prime minister himself benefited. Only weeks before his message to Brussels, Cameron had given a speech to the Conservative conference assuring anyone listening that “this party is on the side of working people”, and rather condescendingly identifying the latter as those who set store by “never giving up, working those extra hours, coping with those necessary cuts”.

 “We build a land of opportunity,” he insisted. But in the letter, he specifically suggested to Herman Van Rompuy that offshore vehicles used for what high-end financial advisers call “inheritance planning” might best be left alone. Cameron and Osborne’s supposedly exacting approach to public finances obviously had its limits. And the prime minister clearly had a keen sense of his core constituency. As one wag put it on Twitter this week, “How fortunate for people with money in offshore trusts that the prime minister went out to bat for them.” Quite so.

Hypocrisy?
