Bloomberg News is reporting that Bob Shrum, the veteran U.S. pollster and campaign adviser, was paid by the Smith Institute to formulate an anti-Cameron campaign strategy for Gordon Brown.

They have obtained a transcript of a speech given to a private Smith Institute invited audience, which included Brown acolytes Ed Balls and Douglas Alexander, as well as other media allies. Shrum advised the Brownites to brand Cameron as “an empty opportunist who will do anything to win”.

The event was held to review Cameron’s first 100 days in March 2006.

Guido understands that a formal complaint to the Charity Commissioners requesting a full-scale investigation of the Smith Institute under Section 8 of the Charity Act will be considered by the Charity Commission today.
