National Savings & Investments has said that in the event of Scottish independence people living north of the Border will no longer be able to invest in Premium Bonds or other NS&I accounts - unless they have a bank account with an institution in the rest of the UK.

Investors could keep their existing holdings, but new money would have to be turned away from people with solely Scottish bank accounts.

NS&I, which is regulated directly by the Treasury has said its rules would need to change if it were to allow savers in an independent Scotland to invest new money.
