THE family of former businessman Sean Quinn were in a Dublin court today seeking to add the Department of Finance and the Irish Central Bank to their case against the former Anglo Irish Bank.

They claim the Department of Finance and Central Bank conspired with Anglo in its advancing of more than �2 billion in loans to companies owned by Mr Quinn for the unlawful purpose of propping up its share price.

The allegations were made during a sitting of the Commercial Court.

In an affidavit, Mr Quinn's daughter Aoife said the department arranged for documents to be "significantly amended" to disguise the extent of its knowledge that Anglo had unlawfully loaned vast sums to support the bank's share price.

The Quinns want the Department and Central Bank joined as co-defendants with Anglo in their action denying liability for those loans.
