To say "The subsequent recession post 2010 was caused purely by the coalition's unnecessary austerity programme." is absurd when the Labour government had to borrow a record and staggering £163,000,000,000 (£163 Billion pounds) in 2009-10
http://news.bbc.co.uk/1/hi/business/8636701.stm. To put that figure of £163 Billion in context. The entire national debt in 1997 when Labour took power was £350 Billion.
Brown stuck to the manifesto commitment to not exceed the Tory spending plans from 1997 to 2001, resulting in £41 billion of debt being paid off by 2001. However after 2001 Brown massively and unsustainably increased spending with the effect that we were increasing the national debt in the (debt fuelled) fake boom years of 2002-2007, mistakenly thinking the boom was sustainable. It wasn't, it was a wholly unsustainable boom caused by excessive government spending resulting from government borrowing and excessive personal spending funded by excessive personal borrowing.
