A deal setting out terms for a Scottish independence referendum has been signed by Prime Minister David Cameron and First Minister Alex Salmond.

The agreement, struck in Edinburgh, has paved the way for a vote in autumn 2014, with a single Yes/No question on Scotland leaving the UK.

BBC's political editor Nick Robinson reports from Edinburgh on the possible implications.
