CITY council leader Steve Brady has accused Prime Minister David Cameron of "bandwagon jumping" over plans by Siemens to open an offshore wind turbine factory in Hull.
During a visit to one of the company's plants in Lincoln on Tuesday, Mr Cameron said he believed the German engineering giant would be making its long-awaited final decision over the proposed Hull facility "maybe today, maybe tomorrow".
As yet, Siemens has declined to comment on whether a decision is imminent.
Councillor Brady said he believed the Prime Minister's comments were inappropriate.
Speaking at a full council meeting, he said: "The term 'bandwagon' comes to mind when I hear these sort of things being said.
"We hear all this talk from someone looking to take all the credit for the decision.
"In contrast, what have you heard from Hull City Council? Absolutely nothing because we know the right way to go about things.
"We know how important it is to work closely and quietly on this, hopefully following things through with investment in the city.
"All I will say is that we continue to make significant progress with Siemens on Greenport Hull.
"We certainly don't want anything causing problems when people announce things that have yet to happen."
While remaining optimistic over Siemens, Cllr Brady said he was disappointed at the Government's response to Lord Heseltine's recent report into ways of boosting regional economies.
The Tory peer has called for more power and Whitehall funding to be given to Local Enterprise Partnerships and councils.
In his spending review announcement, Chancellor George Osborne allocated £10bn to supporting recommendations in the report over the next five years.
However, Lord Heseltine, who has chosen Hull to pilot some of his ideas, had called for at least £70bn to support his report's findings.
Cllr Brady said: "In effect, the Heseltine report has come to nothing.
"The £2bn-a-year is just money that would have come to local authorities anyway."
Opposition Conservative group leader Councillor John Fareham said Lord Heseltine's solutions deserved more support from ministers.
"The only time the hall at the recent Local Government Association was packed was for Lord Heseltine," he said.
"It was standing room only because he had something interesting to say and he is right in what is he saying on this."
