The Forum of Private Business (FPB) is calling for politicians to "educate themselves" on the issues facing businesses across the UK.Comments came after a study by Equifax revealed that only 13 per cent of political representatives had experienced more than five years in business.The FPB’s chief executive, Phil Orford, said: "The fear shared by many business owners is that the legislators responsible for the red tape that hinders them so much do not even begin to understand their needs."Equifax’s latest Business Failures report also found that company closures had increased by 9.1 per cent in the first quarter of 2008, compared with the same period last year.Neil Munroe, Equifax’s external affairs director says that "tough times" are ahead for businesses."Banks are going to look at businesses just as closely as they are looking at individuals, making it harder for firms to get funding to pay off debts and bolster cash their flow," he explained.The FPB currently represents 25,000 private businesses across the UK.
