David Cameron wanted a clear decision on independence but said on a visit to Edinburgh in February 2012 that, “when the referendum on independence is over, I am open to looking at how the devolved settlement can be improved further. And, yes, that does mean considering what further powers could be devolved.” The emphasis then was only after the referendum. That only changed earlier this year as the three unionist parties produced their separate, and very different, proposals for more devolution. The second question was kept on the table during the negotiations by the SNP partly as a fall-back position and partly to keep up the pressure.

The First Minister, who until now has confined his comments to saying he is open-minded about a second question, also said there was a "very attractive argument" for devo max.
The remarks, made recently in America, come amid growing speculation that Salmond intends to defy Westminster by including a second question about enhanced powers in the 2014 ballot.
Opinion polls consistently show more Scots support extra powers for Holyrood over independence.
Devo max offers Salmond a way to avoid defeat in a straight Yes-No referendum, as well as being a major stepping stone to independence.
Pro-Union parties say a second question is a desperate SNP fallback, which would muddy the issue of Scotland being in or out the UK, and could expose the referendum to legal challenge.
The UK Government, which wants a simple Yes-No on whether Scotland should leave the UK, has offered Edinburgh a new power, known as a Section 30 order, to make the referendum immune from legal challenge.
