One of the new schools, Rhosnesni High, opened last week

Councillors discussed the conclusions of an internal inquiry into the issue at a meeting held behind closed doors on Monday.

But the authority will not reveal whether any staff have been disciplined, saying all personnel matters are dealt with in confidence.

The cost of the project was originally put at �12m but this rose to �22.5m.

It was first revealed last autumn that the cost of the project had doubled and a thorough inquiry was promised.

One of the new schools, Rhosnesni High, opened at the start of this term.

Council leader Neil Rogers said at the opening that the project was still value for money, in spite of the cost hike.

He said the increase in costs was due to an 'underestimate' and not an 'overspend'.

"Although there have been some setbacks along the way I believe that this project represents value for money and a new era for secondary education in Wales," he said at the time.

Pupils at the second 'superschool', Ysgol Clywedog, are being taught at the old Groves school until building work is completed.

It is on schedule to reopen after the Christmas holiday.
