How will Cameron deliver constitutional change to UK?

The UK government's focus will now be on how it delivers its promise of more powers for the Scottish parliament, based at Holyrood, Edinburgh.

The three biggest UK-wide political parties - the Conservatives, Labour and the Liberal Democrats - signed a pledge to devolve more powers to Scotland, if Scots rejected independence.

There is also the issue of whether MPs with seats in Scotland, Northern Ireland or Wales should continue to be allowed to vote on legislation that will only affect people in England.

UK political parties will now have to work through their differences to achieve significant constitutional change.
