The Government has received a review it commissioned from the independent Process Auditor to the National Broadband Plan on the integrity of the project's procurement process.
The report by Peter Smyth has examined whether contacts between former Minister for Communications Denis Naughten and David McCourt, the businessman leading the only consortium left bidding for the contract, have undermined the plan.
"Mr Smyth's review has been received and we are in consultation with the Attorney General's office," a spokesperson for the Department of Communications, Climate Action and the Environment said.
"There is no further comment at this time."
The probe was requested by the Taoiseach on 11 October after Mr Naughten resigned after it emerged that he had met Mr McCourt a number of times while the procurement process was continuing.
One of the meetings took place in Mr McCourt's home in Co Clare and was not minuted.
While the procurement process for the National Broadband Plan is under way, all those involved must abide by a strict communications protocol in order to protect the integrity of the process.
Mr McCourt is the founder and chairman of Granahan McCourt, the company leading the National Broadband Ireland consortium.
It is the only remaining bidder for the troubled National Broadband Plan after eir and SIRO withdrew from the process last year.
The project team at the Department of Communications is currently evaluating the tender submitted by National Broadband Ireland.
