This paper offers a guide to what powers and controls the devolved nations hold, and what has been promised as Scotland goes to the polls.
While Scotland goes to the polls to vote for or against independence, other regions and cities in the UK are calling for more powers to be transferred from Whitehall.
This briefing broadly sets out the powers each of the devolved governments currently holds, as well as London, which has more powers than any other UK city. And it provides a brief summary of the pledges that political parties have made so far to Scotland, Wales, Northern Ireland and London in the run-up to both the Scottish referendum and the general election in 2015.
