If the thing I read yesterday is true, Norway pays 90% per person of what the UK does, making 'little' = 10%. Except we get handed back nearly half that money and I rather doubt Norway get EU subsidies or rebates.
So the Norway deal appears to give them EU regulations, they're Schengen anyway so free movement is neutral, they probably pay more than we do & have no influence from that payment. Sounds like a pretty poor deal, a high price to pay for letting local incompetent or dishonest politicians & civil servants make a few decisions some other crooked and incompetent ones makes now.
Farrage&co of course hope brexit has them supping closer to the trough and getting a good deal for the country is the last thing on their minds.
