Scottish independence: Public spending row

SNP ministers and the UK government have disagreed on the finances of an independent Scotland in a row over public spending.

Prime Minister David Cameron has said reform of the Barnett formula, which determines Scottish public spending, is "not on the agenda".

Mr Cameron has refused to give a longer-term guarantee prompting protests from SNP ministers.

The Treasury has also claimed that the plans in the independence White Paper would cost Scotland an additional £1.6bn. A claim that has been dismissed by Deputy First Minister Nicola Sturgeon.

BBC Scotland's political editor Brian Taylor reports.
