I am at the Gleneagles hotel, where the G8 leaders are meeting. On the bus here from Edinburgh, we heard rumours of explosions in central London. The news services are covering this, with Reuters and AP keeping fingers on the pulse.

The UK delegation here are yet to issue a statement, simply saying "wait and see". Aid, trade and debt are off people's lips for the first time in weeks. As this block is rammed with journalists, speculation is rife. As soon as anything is confirmed here, I'll post again. British Prime Minister Tony Blair is due to make a statement at 12 noon GMT.
