Looking after the pennies

So the outstanding debt of the UK Government has reached the sum of £1 trillion.  That's £1,000,000,000,000, I think.  Seems a lot.

But The New Statesman has a handy graph to put it in perspective:

Expressed as a percentage of gdp, the debt may be higher than in the last 40 years, but lies well below the position during the period from the Great War to the 1960s when, if you remember, we never had it so good.
