Berlent, where on Earth did you get those figures from???????????

In the 2010 Budget, Government revenues total QR88.7bn, and the budget will be in deficit totalling QR5.8bn.

In other words, the government plans to spend US$1,590,000,000 more than it plans to earn in FY2010.

Update: Okay, so you're basing your argument on calculations made when oil was at $147/barrel.

You might want to watch Bloomberg a bit more often.

And quoting 2008 estimates midway through 2009 isn't a good way to win arguments.
