LONDON - JULY 30: John Chilcot, chairman of the Iraq Inquiry, holds a news conference to outline the terms of reference for the inquiry and explain the panel's approach to its work during a news conference to launch it at the QEII conference centre on July 30, 2009 in London. The head of a British inquiry into the Iraq war said Thursday he will call former Prime Minister Tony Blair to testify about the run-up to the conflict, but acknowledged it is unlikely that senior Bush administration officials would give evidence.
