A random idea I had but what effects, if any, might there be to the UK having a sovereign wealth fund funded by North Sea oil income similar to Norway's? I was thinking something along the lines of the Conservatives passing legislation in 1995 mandating that from 1996 onwards all oil revenues have to go into the fund, partly as a way of trying to regain their reputation for fiscal responsibility and partly to tie the hands of any future Labour governments. The elephant in the room is of course Scottish independence since the SNP claiming a 'fair' share of it for any prospective future independent state might help bolster their economic arguments, but I was interested to see what else people might be able to think of.
