A decision on the multi-million pound Circuit of Wales racetrack faces yet another delay – with Welsh ministers accusing the developers of providing “inaccurate” information on the plans.
The company behind it has asked for a £210m taxpayer-funded guarantee – about half the cost of the scheme.
The firm said it had responded to every question on a “complex project with thousands of pages of information”.
Plaid Cymru said ministers wanted a delay until after the general election.
A decision was initially expected in March, but the Welsh Govermment has now said the process will take “a final few weeks”.
Although the track near Ebbw Vale would be privately funded, the developers – the Heads of the Valleys Development Company – have asked the Welsh Government to guarantee around half the £425m cost.
In a written answer, Economy Secretary Ken Skates said officials and external advisers “identified many material gaps and inaccuracies in the information contained within the Circuit of Wales application”.
Final submissions were received in the last week which will allow an analysis of the plans to be completed.
“This further delay has meant the timescale asset in March has slipped,” Mr Skates said.
“I am advised that the remaining process will take a final few weeks, following which cabinet will consider the project as soon as is practicably possible.”
The disclosure came in an answer to Plaid Cymru AM Adam Price, who accused the Welsh Government of “dissembling and delay”.
“Having originally said they would make a decision after the local council elections in May, they are now, it seems, seeking to postpone any announcement until after June 8 – and blaming the company in the process,” he said.
“The conclusion you are forced to make, based on this answer, is that they have made their minds up but are seeking to bury bad news until after the election.”
In February, Mr Skates said the plans would be looked at thoroughly as part of a due diligence process that would take four to six weeks.
Later, he said no decision could be made before mid-May because the company had not provided all the information required.
The project has already had more than £9.3m in loans and grants from the Welsh Government.
In April, the Wales Audit Office said there were “significant shortcomings” in the way that funding was approved.
The Circuit of Wales said in a statement: “The development is a complex project with thousands of pages of information and we have responded to every additional question asked by the Welsh Government during the due diligence process, a process that is complex and time-consuming and amounts to a forensic scrutiny of every aspect of the company’s proposal.
“We look forward to a positive announcement in the coming weeks that will allow us to commence construction on a destination that is being fully funded by the private sector and will have a transformational impact on the south Wales valleys region and deliver investment and new full-time sustainable jobs.”
