More than 60 per cent of business leaders in Cambridgeshire want the UK to stay in the European Union according to a snap poll.
The figures released by Cambridgeshire Chambers of Commerce indicated that 63 per cent would vote to remain while 25 per cent said they would leave and 10 per cent were undecided.
Chief executive John Bridge OBE DL said: "Successful businesses operate on facts, figures and forecasts, and to date all of these seem to be noticeably absent from both campaigns.
"The message from our members is that the lack of information and informed debate is preventing voters from shaping their own views."
The results were released on the same day as a national poll, conducted by the British Chambers of Commerce, which showed that around 54 per cent of those asked would vote to stay in the EU and 37 per cent would vote to leave.
Mr Bridge added: "Right now many feel that they simply don't know what they're voting for and are becoming disillusioned by the increasingly futile Punch and Judy show being played out by politicians in the media."
