The question itself is famously attributed to the then Labour MP for West Lothian, Tam Dalyell, who raised it in 1977 when Jim Callaghan's Labour government proposed a devolved assembly in Edinburgh.

Put simply , it asks why Scottish, Welsh or indeed Northern Irish MPs have the same right to vote at Westminster as any English MP now that large areas of policy are devolved to national parliaments and assemblies in areas such as health, housing, schools and policing.

Often translated as "English votes for English laws", the question also comes up if non-English MPs become UK ministers and push through controversial England-only measures, even as their devolved government rejects them.

What should follow the Scottish "no " vote and further devolved powers should be a devolved English parliament, with full legislative powers, akin to the Scottish Parliament. We have heard from Scotland its England's time now, expect UKIP to make great capital from this in the coming months.
