In March 2003 the UK entered the war in Iraq alongside the United States and other forces, a war which resulted in the death of hundreds of thousands of Iraqi civilians, and 179 British troops among thousands of other military casualties.
YouGov has conducted tracker polls over the years which highlight the changing attitudes to the war, as the majority of the country shifted from support, to condemnation.
Increasingly, more people are unsure, as currently 23 per cent don't know what their stance on the war is.
This trend has coincided with the rise of Isis in the region, over the past year or so.
The Iraq body count project estimates that documented civilian deaths in Iraq since the war began could be as high as 159,580.
