OTTAWA - Brian Mulroney's lawyer says there's no evidence that would compel the former prime minister to return to the Commons ethics committee for a second round of testimony.

Guy Pratte says German-Canadian arms dealer Karlheinz Schreiber's own testimony is contradictory and points to Mulroney's innocence.

Pratte told a news conference today that it's evident the motive behind Schreiber's testimony has been to avoid or delay his extradition to Germany where he faces fraud and tax-evasion charges.

Mulroney's lawyer also says there is no evidence that warrants a public inquiry into the matter but, if there is one, he's prepared to co-operate fully.

Committee testimony has centred on a series of cash payments Schreiber made to Mulroney for promoting a project to build German-designed, light-armoured vehicles in Canada.

Mulroney says he took $225,000 after he stepped down as prime minister; Schreiber says the payments totalled $300,000 and the deal was struck just before Mulroney left office.

Mulroney has said the money was compensation for lobbying international leaders whose countries might buy the vehicles.

Schreiber insists the agreement was for Mulroney to lobby the Canadian government -- which could have put the former prime minister in violation of federal ethics rules.
