Former foreign secretary Jack Straw has admitted he still gets called a "war criminal" by members of the public.
Mr Straw, who was in office when the invasion of Iraq was authorised by MPs in 2003, also said it was "unfortunate" the long-awaited Chilcot inquiry was taking so long.
In an interview with the Daily Telegraph, Mr Straw said:
Sir John Chilcot confirmed last month his inquiry, which began six years ago and has cost millions of pounds, would not publish its report ahead of the general election in May.
George Bush being elected US president was "the worst thing ever to happen to Tony Blair", according to former foreign secretary David Miliband.
Speaking on ITV's The Agenda programme, Mr Miliband contrasted the period in the lead up to the US-led invasion of Iraq a decade ago with the lead up to the US-led invasion of Kosovo under the stewardship of Bill Clinton.
Reflecting on the 10th anniversary of the Iraq war, David Miliband told Tom Bradby on The Agenda, that:
"If the message to dictators around the world is that the West will never intervene - and that's the message that President Assad of Syria has got today - we're going to live in a very very dangerous world."
Tony Blair was the only man with the power to stop President Bush from invading Iraq in 2003, former UN Secretary-General Kofi Annan has claimed.
Mr Annan said unlike himself and then US Secretary of State Colin Powell, Mr Blair had the ear of President Bush ahead of the war and could have acted.
Speaking to The Times (£), he said: "I think I will for ever wonder what would have happened if, without a second [UN] resolution ... Blair had said 'George, this is where we part company. You’re on your own."
Mr Annan added: "I really think it could have stopped the war ... It would have given the Americans a pause. It would have given them a very serious pause to think it through ... All this would have raised a question: ‘Do we go this alone?’"
