The number of bosses who can see green shoots appearing in the economy has doubled since February, according to a ComRes survey for The Independent. Some 37 per cent of business leaders now detect signs of recovery in their company’s sector – up from 32 per cent last month, 29 per cent in April and 18 per cent in February. But the survey of 203 businessmen and women suggests that the Government is getting little political credit. The ratings of both Gordon Brown and Alistair Darling have dropped in the past month. Only 14 per cent of them have confidence in the Chancellor, his lowest rating since last September when the financial crisis broke out. Only 24 per cent think he understands business and only 26 per cent believe he is handling the economy responsibly.
