So apparently the Lisbon treaty which appeared to be done and dusted will actually be back before parliament in a few weeks time for technical ratification of a few points regarding seat distribution that had to be rushed through previously.
Now at first glance this may seem like a golden opportunity for David Cameron. He always said that he wanted a referendum on Lisbon and in a few weeks time he may well be Prime Minister. The question is what will he do?
There are suggestions that he could announce a referendum and then use that as a bargaining chip with the rest of the EU about repatriation of powers.
I think that David Cameron will actually view this situation with dread. He thought that Lisbon and the EU were now well and truly kicked into the long grass. This would bring it all to the fore again. Worse still it is likely even if the Tories can get a majority that it will be pretty slender. We all know that there are a sizeable chunk of Tory MPs (and many current PPC who may well be MPs on Friday) who would actually like to see us renegotiate the UK's position in the EU in a much more fundamental way. These MPs could find themselves able to exert great pressure on Cameron to make any referendum more wide ranging.
If instead the Tories do not have a majority (which is currently the most likely outcome according to the bookies) then Cameron may not even have enough votes in the house to call a referendum or block ratification. I wonder how Tory MPs would react to that.
Things could get very interesting on this front very quickly.
