Short term car insurance - implications?

If I allow my brother insure himself to drive my car using one day internet purchased car insurance:

Would I have to tell my existing insurance company that he has insured himself, would I have to tell them if he had a claim and what would be the consequences for my own NCD and premium if he had a claim?

Yes, yes and if he has a claim while driving your car it will affect your premium even though it happened on his policy.
