It always amazes me that everyone seems to know about insurance regardless of their knowledge. Perhaps you can explain why public liability insurance isn't available to me.
If I cycle and I cycle into someone and injury them or their property, who I not need public liability insurance to pick...
I would have thought that the first questions that need to be asked are:
1. Who has told the organizers that PL cover is required.
2. What PL Limit of Indemnity is suggested or required as a minimum
3. Are any terms and conditions stipulated by who ever says everyone needs it.
No point doing...
