UK party leaders pledge new powers for Scotland if it votes No. But what could they be?

David Cameron, Ed Miliband and Nick Clegg have signed a joint declaration — carried on the front page of today's Daily Record — guaranteeing "extensive" new powers to the Scottish government in the event of a No vote.

What these powers might be is uncertain since each of the three UK parties has their own proposals. At the very least, it seems likely that Scotland's power over setting income tax would be extended in some form even if full independence is rejected.

We set out earlier this week just what powers Scotland has now, and what could be on offer if Scotland votes No on Thursday.

The three UK party leaders also guaranteed that:

"... because of the continuation of the Barnett allocation for resources, and the powers of the Scottish Parliament to raise revenue, we can state categorically that the final say on how much is spent on the NHS will be a matter for the Scottish Parliament".

We plan to publish a piece which addresses funding for the NHS in Scotland within the next day.
