UNION leaders last night demanded they be shown a crucial report into the state of steel-maker Corus.

The Anglo-Dutch firm brought in McKinsey management consultants last month to produce a study of the various assets, strengths and weaknesses of the UK operations.

Now the GMB union has called for an unedited copy of the document to be released to show where the problems lie.

Kevin Curran, regional organiser, said: "The GMB will not stand by and see our member's jobs thrown on to the scrapheap because of fat cat mismanagement.

"The GMB will fight any compulsory redundancies all the way and reject any attempt to reduce our current steel capacity.

"Our members are in no way to blame for this situation and Corus should realise that if it involved and consulted the workforce before making poor decisions it might not be in the mess it is now."

Corus has been in turmoil - struggling to repay debts of £1.2bn and failing in its attempts to convince the Dutch supervisory board to allow it to sell its aluminium operations to French firm Pechiney.

Matters came to a head last week when chief executive Tony Pedder resigned in the wake of massive operating losses.

The results compounded concerns raised when Corus announced it would have to cut back production and possibly close part of its operations in a last-ditch attempt to return to profitability.

Mr Curran said: "Managerial changes are long overdue at Corus. We need to be able to deal with people who we can trust and can deliver. Corus can make a start by getting rid of chairman Sir Brian Moffat immediately.
