Chilcot said in his letter to the prime minister that the report will be more than two million words long. That means the final document will be four times bigger than Tolstoy's War and Peace and more than double the size of Ayn Rand's Atlas Shrugged.

The investigation is expected to draw on a staggering 200 cabinet and cabinet committee meetings.

Chilcot's report is 'much awaited' for good reason. The inquiry completed its last hearing in February 2011. With a publication date of summer 2016, that means it will have taken seven years to finish the report.

That's how many results you receive on Google when you type in 'Tony Blair and Chilcot'. The former Labour prime minister, who took the UK into the Iraq intervention in 2003, has become synonymous with the report.

Blair's office stressed that he wanted to make clear that the lengthy timetable of the inquiry was not his fault. The remarks come after Blair made a qualified apology on CNN for the war.
