I really don't get how you find it so hard to understand a relatively simple graph and quote from the independant report a Labour support here highlighted and then you say i'm arguing in bad faith. What does that have to do with Saint Jeremy promising free stuff to everyone and evil Tories having to try to get the debt run up by the previous labour government under control. You seem confused.And you've been asked to consider what might have happened in 2008 that caused that debt.
"In the past eight years, debt has increased to 80% of GDP, but is beginning to stabilise"
