Investigation of the year was the most popular category at the 2012 British Journalism Awards with more than 40 entries.
The judges were particularly impressed with the quality of work on display and so opted for a longer eight-strong shortlist.
Winners: Alexi Mostrous and Fay Schlesinger (The Times)
Weeks of planning led to Mostrous and Schlesinger’s covert recording operations which exposed the tax avoidance techniques of the rich and famous.
Their first investigation titled The tax avoiders detailed how the biggest beneficiary of the K2 tax scheme was comedian Jimmy Carr.
Taxman v. Take That exposed a music investment scheme used by the members of pop group Take That.
Screenplay: how movie millions are moved off shore explained how wealthy City investors are secretly moving tens of millions of pounds offshore using tax efficient film finance schemes.
Judges said: “This was an investigation which was clearly both interesting to the public and in the public interest. A brave and determined investigation which exposed high profile rich figures who were effectively stealing from the poor.”
