The Tánaiste Joan Burton says she hopes the interim report of the inquiry into the IBRC will be published this week.

The report will form part of the Government decision on how to proceed with the investigation after the judge said he had run into issues with confidentiality and legal privilege.

Justice Brian Cregan said his legal investigation had reached a legal brick wall, partly because the Department of Finance claimed some of its documents were covered by confidentiality.

But in a lengthy statement last week, the Department of Finance said it has cooperated fully - and said it was right to give that warning to Judge Cregan's inquiry.

While the Taoiseach said he would be breaking the law if he engaged with the Department of Finance about what they have or have not provided to the inquiry into write-offs at the IBRC.

Fianna Fáil leader Micheál Martin last week accused Enda Kenny of using 'Chinese walls' to deflect from the situation.

But Tánaiste Joan Burton says she hopes the matter can be discussed by Government soon.
