"But since when have labs been interested in the truth!!"
Turn it up. Since when has either side been interested in the truth. You've fallen into the pollies favourite trap. When in opposition quote gross debt. When in power, they quote net debt. Both sides play this game, but it's the net debt that counts. It's currently equivalent to about the same as the spare change underneath the cushions. Distinguish between the two and you won't be taken in by the spin.
