If you mean the West Lothian question, AOG, I think it's less of an issue to us than it is to Wales and Scotland. On a large number of issues 40 MPs in Wales, let us say, tend not to be enough to swing an issue one way or another (and how often do they vote the same way anyway?). By contrast there are 533 MPs in English Constituencies (about 5/6 of the total Mps), so if ever there were a bill that affected only Wales, every Welsh MP could vote against it but still be massively outvoted, but in the reverse case English MPs could easily stop the Welsh, Scots and Irish imposing their will on us.
It's just not an equal relationship -- and so the need for a purely English Parliament is far less than for a Scottish one. Since when was England fully united on every issue anyway? You might just as well say that the people of Yorkshire are being imposed on by the rest of the country, so maybe we should have a purely Yorkshire Parliament. ('E by gum, tha's no' a bad idea, like!)
