This section applies to bankruptcy debts owed in respect of credit provided by a person who (whether or not the bankrupt's spouse or civil partner at the time the credit was provided) was the bankrupt's spouse or civil partner at the commencement of the bankruptcy.
Such debts—
rank in priority after the ... interest required to be paid in pursuance of section 328(4), and
are payable with interest at the rate specified in section 328(5) in respect of the period during which they have been outstanding since the commencement of the bankruptcy;
and the interest payable under paragraph (b) has the same priority as the debts on which it is payable.
