I actually don't know the answer to that question specifically, because the cost of it has varied over the years depending on the particular financial arrangements that the British government has contracted with the private companies, so there isn't an easy figure to put on that, and I certainly don't know what the figures are for Sweden.
I've heard that the current figure for GPS in England would be £2 a day. These would be the pilot projects that are running at the moment with persistent and prolific offenders. It's £2 a day to run a GPS tracking system on very high-risk offenders. I can say that because the person who is involved in that project gave me this figure quite recently, but other than that I can't give you a hard and fast figure on the daily cost.
