George Osborne is the one "issuing threats", said the SNP's deputy leader over a bid to block a currency union with an independent Scotland.
Nicola Sturgeon told Andrew Neil that she wanted Scotland "to pay its fair share of debt", but added that it could not default on debt "that is not legally Scotland's".
Scotland's deputy first minister was also asked about the costs to be charged to students from the rest of the UK who would attend universities in an independent Scotland.
