I still think it's a massive gamble, however opinion seems to be moving slowly more to staying in than coming out of the EU.
I cannot though see him winning the next election with an overall majority so he is near for sure unlikely to be able to deliver such a referendum.

He risks opening up a great divide in the Conservative party too and divided parties do not do well in General Elections at all.
In such a referendum, I would vote to stay in anyway.
Risky and unwise,he has been badly advised on this in my opinion.
