I want to know the answer to the following question:
How much did security cost for the torch relay in London?
All the background I'm provided with is that "A Metropolitan police briefing paper revealed that security for the torch relay cost £750,000 and the participation of the Chinese security team had been agreed in advance, despite the Mayor stating, "We did not know beforehand these thugs were from the security services.". Is that enough to answer the question?
Answer: yes
