David Cameron, the British prime minister, has delivered an impassioned speech urging Scotland to remain part of the United Kingdom.
Visiting Edinburgh ahead of negotiations between the two countries over a Scottish independence referendum, Cameron said England and Scotland could survive apart, but work "so much better together".
Scotland has had significant autonomy since 1997, when the Edinburgh-based Scottish Parliament was set up. It has full control over the education, health and justice sectors.
Total independence, however, would give Edinburgh control over energy policy relating to the North Sea, plus the ability to raise taxes.
And, more crucially, it would also allow Scotland to pursue its own foreign policy. Al Jazeera's Laurence Lee reports from London, the capital of the United Kingdom.
