OTTAWA - The Commons ethics committee is poised to deliver a final report summarizing its hearings on the Mulroney-Schreiber affair.

The committee is calling on Prime Minister Stephen Harper to get on with a full-fledged public inquiry as soon as possible.

Sources say all parties on the parliamentary panel are agreed on the need for a follow-up inquiry, and that view will be reflected in the report to be tabled in the full Commons today.

But there were differences of opinion on fine points during a closed-door committee session Tuesday, and it appeared minority reports could also be presented on some issues.

Insiders say some Conservatives appeared to balk at proposed wording that called on Harper to set as wide a mandate as possible for the new inquiry.

The Bloc Quebecois wanted to include comment on the credibility of certain witnesses who appeared at the hearings.

And the NDP was considering the possibility of a "supplementary'' report that would agree with the main findings but tack on some additional observations.

At issue are the business dealings between former Tory prime minister Brian Mulroney and German-Canadian arms dealer Karlheinz Schreiber.
