7.4 million votes counted so far, and it's split 50.0% / 50.0%
ITV news in London has called a 75% Brexit win
Hoooooooooooooooooooooooooooooray! 
i am concerned, if GB leaves others will follow and that's not something to be too happy about imo. a dismantling EU is a security risk.
I think it's quite unlikely others will follow. Especially not if Scotland leaves the UK and joins the EU.
the mood is against EU in alot of countries and a Brexit will give them momentum and better arguments. the call for referendums will get louder in france, netherlands, finnland, spain, italy, whatever. scotts will eventually leave GB and join a club that is disassembling.
Indeed, the mood is against. But those countries will never have a majority that vote to leave.
