To take an example of relative decline of the left we will know the extreme right has evolved into a new force if it is capable in the UK of making common cause between the native english and the first and second generation Irish. Many Irish still have ties to the homeland through family even to third generation thats a huge demographic of potential voters who are naturally rural conservative. I see it more and more that BNP and extreme types talk of more hazy concepts like judeo-christainity blah blah and allowing people from the "Home Islands" as they style them to stay.
