Chris Jefferies, who was wrongly arrested on suspicion of murdering Joanna Yeates, will later give evidence to the Leveson Inquiry into press standards.
Mr Jefferies won "substantial" undisclosed libel damages from eight newspapers over allegations made against him over the landscape architect's death.
The retired school teacher was the first suspect to be arrested over the 25-year-old's murder and was questioned for two days before being released without charge.
Singer Charlotte Church , broadcaster Anne Diamond , former British Army intelligence officer Ian Hurst and Northern Ireland human rights campaigner Jane Winter will also appear as witnesses at the inquiry.
On Sunday a political blogger was summoned to appear before the inquiry after evidence from ex-No10 communications chief Alastair Campbell was leaked online.
Mr Campbell submitted papers containing a string of potentially damaging claims to lawyers ahead of his appearance before Lord Justice Leveson this week.
But a link to the 16-page document appeared on the Order-order website run by Paul Staines, under the name Guido Fawkes.
Writing on his blog, Mr Staines highlighted contentious elements in Mr Campbell's evidence and claims to have obtained the papers legally.
Mr Campbell, who is due to appear at the inquiry on Wednesday, said he was "genuinely shocked" to see his evidence in the public domain.
At the last hearing on Friday, the inquiry heard moving evidence from Madeleine McCann's parents.
Kate and Gerry McCann described how suspicion surrounding them led to a barrage of highly personal media reports.
Mr McCann told the inquiry there were "sinister reports" circulating about the couple's involvement after their daughter vanished in 2007 and the reporting quickly became highly speculative.
Mrs McCann told of her distress at reports that her daughter was dead and said she felt her voice carried no weight against the power of the media.
The witness schedule:
:: Tuesday, November 29
Guardian reporter Nick Davies, former News Of The World journalist Paul McMullan, and former Daily Star reporter Richard Peppiatt.
:: Wednesday, November 30
Alastair Campbell, spin doctor to Tony Blair and former Daily Mirror journalist.
