Business bosses in the West Midlands fired out the message "we'll believe it when we see it'' after Gordon Brown unveiled his huge cost-saving regulations shake-up.
A snap Birmingham Post poll of regional representatives at the two day conference - at the Business Design Centre in Islington, London - showed most people welcomed the principle of the moves.
But nearly everybody had doubts over his ability to deliver.
Jeremy Woolridge, chairman and chief executive of Wedge Group Galvanizing, which employs 750 people in the UK and 150 at Willenhall, said: "It's always nice to come to these events with a good headline. We'll have to wait to see how this really pans out. On the face of it - tremendous news. But just how will it impact across the board? We shall have to wait and see.''
Trustee of Birmingham Botanical Gardens Bill Good, a one-time Black Country industrialist, added: ''The devil is often in the small print.'' And Wedge Group operating director Colin Leighfield was even more blunt. He said: ''We've heard it before, I think Gordon Brown speaks with forked tongue.''
IT specialist Harvey Nash, which employs 250 in Birmingham, was represented at the conference. European managing director Simon Wassall was a key player in setting up the city operation.
He said: "Of course we welcome the announcement because we are all affected by the regulatory burden. As a market leader we take our responsibilities seriously. We'll be looking at these proposals in detail and hope they deliver. Time will tell.''
Angela Stangroom, a spokeswoman for BMW, said regulatory burden cost the firm tens of thousands of pounds across the UK every year.
Reaction to Mr Brown's decision not to implement much of the Operating and Financial Review, which was set to become mandatory from April 2006, was mixed. The OFR would have required companies to detail future strategy and risks, including nonfinancial information and environmental matters, but the disclosure will now be voluntary.
"We're obviously disappointed," said Mona Patel, spokeswoman for the Investment Management Association.
The TUC said it too was dismayed. General secretary Brendan Barber said: "It has been presented as a help to business but the real losers from this are the shareholders who actually own Britain's businesses who will now receive less information."
