Leveson Inquiry: Rebekah Brooks to give evidence
Former News International chief executive Rebekah Brooks will give evidence to the Leveson Inquiry on Friday 11 May, the inquiry has said.
Mrs Brooks was the News of the World editor when voicemails on murdered schoolgirl Milly Dowler's mobile phone were intercepted.
Her successor, Andy Coulson, will give evidence a day earlier.
It comes after a former police officer was arrested by police investigating corrupt payments relating to hacking.
The 57-year-old was arrested, as part of Operation Elveden, at his home in Surrey at 0630 BST on Thursday on suspicion of misconduct in a public office.
Mrs Brooks, who edited the News of the World from 2000 to 2003, has not previously given evidence to the Leveson Inquiry.
She is expected to be asked about relations with MPs and police officers.
After she was asked, in April, to take part in the inquiry, she successfully applied for "core participant" status.
That means she has the right to put questions to other witnesses through her lawyers and also has advance access to witness statements and documents.
Mr Coulson - who resigned as News of the World editor in 2007 after one of his journalists was jailed for phone hacking - will appear on Thursday 10 May.
Appearing on the same day will be Daily Mail and Mail on Sunday owner Viscount Rothermere.
Mail Online editor Martin Clarke will be among those giving evidence on Wednesday.
Mr Coulson went on to become Prime Minister David Cameron's director of communications.
He resigned from that post in January 2011, blaming coverage of the News of the World phone hacking scandal.
In July 2011, he was arrested and released on bail over allegations of corruption and phone hacking.
Mrs Brooks was also arrested in July 2011, and then released on bail, over similar allegations.
She was re-arrested in March on suspicion of conspiracy to pervert the course of justice and was bailed to reappear at a London police station this month.
Inquiry lawyers will not be allowed to ask Mr Coulson or Mrs Brooks any questions that could prejudice the police investigation into phone hacking or any future trials.
