Policy uncertainty in Westminster is weighing heavily on Britain's small business sector, according to one of the City's most influential bankers. Kunal Shah, co-head of Goldman Sachs International, warned that a lack of clarity over taxation and employment laws is creating an "overhang" that is discouraging entrepreneurs from investing and hiring. Speaking to The Times ahead of a House of Commons reception marking 15 years of Goldman's 10,000 Small Businesses programme, Shah said founders were increasingly nervous about the government's shifting regulatory agenda.
