It's official, the national debt is one trillion pounds, or £1003.9 billion if you want to be more precise.
There's nothing much to say about this. It was inevitably going to happen. And in fact if you put back in items which HM Treasury likes to leave out, such as the PFI liabilities, Network Rail's debt and the like, then we actually hit the trillion a long time ago.
However today is the official "trillion" day. Maybe we should have a national holiday on this day every year to commemorate passing this milestone.
