The status quo of FPTP elections will ensure that, without a massive swing to the likes of the Greens and in concentrated areas, the effects will be limited to what the two major parties do policy-wise to prevent leakage of their own support to minor parties.
I.e. it depends on which of the main two parties leaks the most.

As Minty inferred , the grass roots support for both main parties is a million miles away from the views expressed in Westminster. At my local Labour party branch and CLP meetings shortly after the death of TBW the sentiments of my local councilors were in stark contrast to the "if you can't say anything nice say nothing at all" position taken by Ed Milliband. Personally I think Labour has moved too far away from its grassroots membership at national level. Indeed, my former (now retired) Labour MP said at a recent CLP meeting to our current incumbent Labour MP that now he was no longer on the front bench he no longer had to tow the party line.

A sign of how fscked the current political setup is: Labour MP on BBC London News having a pop at Boris because Boris Bikes are having to be partly funded by the public purse.

Partly funded? The majority of the funding is coming from TfL and all after Boris announced it would be funded (in total) by Barclays.

I'd be fooking mad too

Whilst there seems to be no appetite for this floated suggestion, in contrast in the crazy world of those goofy scientists, naming conventions are progressing. Of course, scientists have always had that peculiar, inimitable occasional totally dry humour, but a good example of the modern trends is the case of a 40-million year old extinct 6ft lizard. It has been named [iBarbaturex morrisoni[/i after after the late, great Doors singer Jim Morrison, who older readers may recall was known as The Lizard King, and a 6 foot lizard deffo fits that bill.
