The long-awaited Chilcot Report, released earlier this week, found that the British decision to invade Iraq in 2003 was based on "flawed intelligence" and the invasion went "badly wrong".
While the report stopped short of calling Blair a liar, John Chilcot, who led the inquiry, said that claims about Weapons of Mass Destruction were "presented with a certainty that was not justified".
So after seven years of investigation, was Chilcot hard enough on Tony Blair?
In this week's Arena, Clare Short debates with John McTernan. Short, a member of Blair's cabinet, resigned in the wake of the invasion and has since called the Iraq war a "crime against peace". McTernan, who served as Tony Blair's director of political operations, is a long-standing and outspoken defender of the invasion.
