Labour hits supporters with credit card charge of 18.9% – two-and-a-half times that of market's most competitive option | UPDATED: 02:04 GMT, 30 December 2012 Costly: Labour supporters will be paying through the nose in interest charges on their party's credit cards All three major political parties are profiting from credit cards that charge their supporters exorbitant rates of interest. Both Labour and the Lib Dems offer a card charging interest at nearly 38 times the Bank of England’s 0.5 per cent base rate – and more than two-and-a-half times that of the market’s most competitive card. The card, provided by the Co-operative Bank, charges a standard APR of 18.9 per cent – although richer supporters can have a premium card with a fixed rate of 11.9 per cent for five years.
