Whenever big numbers are thrown around, there is a need to put them in perspective. However, I don't think "number of meals" or "teachers hired" are good or relevant perspectives. The UK police budget is about £3.5 billion. So this expense is about 0.3% of that. The UK budget is about £700 trillion, if I remember correctly. So this expense is about 0.0000014% of that.
Almost, but the GDP of the entire world is less than 10% of £700t.
You're remembering £700b, which is roughly the UK gov't spending.
Whatever the number, a huge chunk of government spending is allocated to this bit of theatre, aimed -- as far as I can see -- at making sure the UK looks like a good ally to the US.
Anyone who thinks this has anything to do with an extradition to Sweden on sex-crime charges is a tool. The UK police don't just drop £10m on extradition compliance for one suspect.
