are all these dips due to selling off public assets? like 1998 is the gold?
It's the opposite, the dips are periods of borrowing (budget deficit).
Notice how 2008 and 2009 were massive deficits as the recession really bit. I wonder if 2008-09 is so large because of the bank bailout (£76 billion was spent on RBS shares, for example)?
Anyway as elmarko says the point is the Conservative party ran a bigger deficit between 1990 and 1996 than the Labour party did 2002-2007.
