Thanks, Peter. Some interesting comments there.
With the IPL being such a high profile league, I agree it's only natural that the spot-fixing scandal would be a concern for the ICC as it strives to protect the integrity of the sport.
I found particularly interesting that a (year old) proposal by Interpol to establish an anti corruption and match-fixing is being reviewed by the BCCI.
Interpol is currently working with FIFA to try to prevent match-fixing in soccer, but the two organisations only reached an agreement to do so a year ago so it's too early to judge how effective the project has been and, arguably, it remains unclear how effective Interpol can be in this field.
Issues like this sting operation should be dealt with by an international body to establish a clear and consistent stance regarding match-fixing, whether that be the ICC alone or working in conjunction with Interpol.
