The extent to which Tony Blair kept members of his cabinet in the dark about his determination to topple Saddam Hussein will come under the spotlight at the Iraq Inquiry today.
Two former cabinet secretaries who served under Mr Blair will be asked about the amount of free discussion the former prime minister allowed on the subject of Iraq before and after the March 2003 invasion.
The inquiry team will also raise concerns about the lack of information provided to some cabinet members. Mr Blair firmly denied he had sidelined those who disagreed with him. However, during his evidence session on Friday, he conceded that some members of cabinet were not shown some key documents detailing Britain's policy towards Iraq.
Lord Wilson, who was the head of the Civil Service between 1998 and 2002, will give evidence. The inquiry will also hear from his successor, Lord Turnbull, who left the post in 2005.
