Thousands of mortgage borrowers could receive a cut of compensation worth a collective £150million if a legal claim at the High Court is successful.
Lawyers at the firm Harcus Parker could take action on behalf of customers who say they were unfairly charged high mortgage rates following the collapse of Northern Rock.
The law firm is said to be representing around 6,000 borrowers who argue they were kept on rates of around 5% for more than a decade even though interest rates plunged to near-record lows after the financial crash in 2008.
