He was speaking after the release of a critical report on the funding of the proposed Wales Millennium Centre in Cardiff Bay.

The National Assembly has to release �15m or more before the project can go ahead.

Mr Morgan said that would not happen until the Assembly had a robust cost estimate for the project.

But Mr Morgan ruled out pulling the plug on the scheme, and said that would only happen if further investigations revealed funding problem "horrors".

The Wales Millennium Centre is still at the design stage

In a statement Mr Morgan said the WMC had been asked to put forward proposals for a �75m scheme and had not done so.

He said he is also talking to the WMC about the need for evidence that the centre can operate successfully when it opens.

"We have to learn the lessons from other schemes that looked fine on paper but were not able to deliver the promised balance between income and expenditure when they opened," Mr Morgan said.

But the WMC said the report was out of date and the problems it highlights were being addressed.

They said the report's authors, in association with others were already working on a new report into the project.
