"The G8 summit formally began at 10 o'clock this morning. But there's been a complete air of unreality about it. The leaders of the world's wealthiest nations are continuing with their formal discussions; they're discussing climate change, and they're discussing the Middle East. But their minds are elsewhere - they're thinking about London and the attacks."
