Former Prime Minister Tony Blair is to appear before the Leveson Inquiry into media standards
The BBC reports that Mr Blair will be questioned over whether his relationship with News Corp owner Rupert Murdoch and the company's News International subsidiary was too close.
Mr Blair travelled to Hayman Island in Australia to address News Corp executives in 1995, as part of a Labour strategy to communicate with newspapers that had unfavourably portrayed previous leaders Michael Foot and Neil Kinnock.
He is also godfather to one of the media tycoon's children.
He previously gave evidence to the Hutton inquiry into the death of government scientist Dr David Kelly - the source for the controversial BBC report about intelligence being exaggerated to make the case for war.
He told the inquiry in 2003 he would have resigned if the claims about "sexing up" the Iraq dossier were true.
In 2010, he said he had "no regrets" about removing Saddam Hussein from power during the Iraq inquiry, which was set up to investigate the run-up to the 2003 invasion of Iraq and its aftermath.
The Leveson Inquiry is currently examining the relationship between the press and politicians.
