On page nine of his latest Statement of Aims and Values, David Cameron promises that his party will "strengthen the United Kingdom by providing a constructive Unionist response to the West Lothian Question."
If this strikes you as woffle, you shouldn't be too surprised, given Cameron's previous policy statement promising that a Tory Government would be in favour of "a strong economy" and "representing modern Britain."
There are in fact only two "constructive Unionist responses" to the West Lothian Question. One is to abolish the Scottish Parliament and Welsh Assembly and return all decision-making to a unitary UK Parliament. The other is to create an English Parliament with equivalent powers to the other two devolved institutions.
It's your call, Dave.
