It has cast a long shadow - the question of whether Tony Blair lied over Iraq.
But today 439 MPs effectively exonerated the former Labour Prime Minister. Just six Conservative and five Labour MPs disagreed.
The SNP chose to use an Opposition Day debate to call for Mr Blair to be investigated again, Scotland's former First Minister Alex Salmond saying the public had been "grievously misled into that disastrous conflict".
But, despite Labour MPs only being subject to a one-line whip (meaning they didn't have to attend), they concluded Mr Blair did not act in bad faith.
Mr Salmond later denied suggestions his move had backfired by uniting MPs in support of Mr Blair.
