Aggrieved business borrowers with National Australia Bank's UK subsidiary will be looking for a sympathetic hearing from the parliament's Treasury Select Committee on their long-standing complaints.Seventy-six members of parliament have endorsed a resolution supporting redress for bank customers allegedly sold "embedded swaps without proper explanation of either the conditions or costs."One alliance of customers, the NAB Customer Support Group said that its "objective is to recover from the bank the difference between the fixed rates we were locked into and the bank's variable rate together with consequential damages."The group contends that, "in a redress scenario, we are talking in terms of billions of UK pounds."Through its Clydesdale Bank brand NAB promoted "tailored business loans", often advanced before the financial crisis at relatively high fixed interest rates. 
According to NAB Customer Support Group the bank's commission model encouraged staff to push this style of loan.The rates no longer suit many borrowers who cannot afford the repayments or the large break fee on the loans.In its trading update for the December 2013 quarter last week NAB said "the risk that additional provisions will be required for UK conduct related matters has increased since the 2013 full year results," and that it would work out how much more was needed over the course of the current quarter.
