The bookies have the odds at 77% for NO BrexitWhile polls are pretty much neck and neck, gamblers seem to believe that there is a very likely chance that Britain votes to stay in the EU.

A spokeswoman for Betfair has said that there is about 43 million pounds ($63.21 million) being wagered on the EU referendum vote.
