OTTAWA - The NDP says it will send G8 Summit documents to the RCMP for a potential investigation of cabinet minister Tony Clement's conduct.

At a news conference in Ottawa on Monday, NDP MPs Charlie Angus and Alexandre Boulerice unveiled new documents - including e-mails between Clement and Huntsville Mayor Claude Doughty - which were obtained through a Freedom of Information request.

Angus said the e-mails suggest Clement used summit money for a personal slush fund and interfered with a spending review.

The ethics critic said he isn't sure if Clement, who is now Treasury Board president, engaged in illegal activities.

"We think that what they have done is broken all the internal rules," he said.

The NDP has asked the Commons ethics committee to probe how money was spent in Clement's riding prior to the 2010 G8 Summit in Huntsville, including a $21-million hockey rink and swimming pool billed as a media centre.

Clement has denied any wrongdoing, but interim auditor general John Wiersema tabled a report in June which found the process for G8 spending lacked transparency. The office, however, has refused to probe further, and the Tories say the issue has been dealt with.

"The facts have not changed. This issue has been thoroughly aired," said Deepak Obhrai, the parliamentary secretary to Foreign Affairs Minister John Baird, who responded for the government on the issue in Question Period.
