The British government announced on Monday that it will take responsibility for all British government debt should Scotland vote to leave the United Kingdom this year.
"In the event of Scottish independence from the United Kingdom, the continuing UK government would in all circumstances honour the contractual terms of the debt issued by the UK government," the Treasury said in a statement.
An independent Scotland would be responsible for "a fair and proportionate share" of Britain's liabilities but a share of the outstanding debt would not be transferred to Scotland, it said, adding the terms of repayment would be subject to negotiation.
Britain's net debt stood at nearly 1.2 trillion pounds at the end of the 2012-13 fiscal year.
