The Chilcot Inquiry into the Iraq war began in 2009 and hearings were completed two years later.
However, the inquiry's report is yet to be published due to repeated delays.
Sir John Chilcot has said that this is to ensure that those criticised have every opportunity to rebut the criticism and that he wants the final report to be published with minimal opportunity for legal action or attack.
Recently, the Labour leadership front-runner Jeremy Corbyn has pledged to apologise for the war on behalf of the party if he wins the election.
With all that in mind, can you remember which of today’s politicians voted in favour of the war at the time?
