One of those heavily overloaded acronyms - in the UK it's Cabinet Office Briefing Room A, which is where all the emergency briefings are done from. So "cobra committee" gets mentioned on the news a lot.
Totally off-topic, but the COBRA panel is now too big to fit in Briefing Room A, and use Briefing Room B now, hence the occasional references to them as Cobr in the press now.
