Harper Alone On Campaign Trail As Trudeau, Mulcair Take Breaks

OTTAWA — Stephen Harper has the national campaign trail all to himself today.

NDP Leader Tom Mulcair and Liberal Leader Justin Trudeau will stay out of the spotlight today while Green party Leader Elizabeth May attends private meetings and a barbecue with campaign volunteers, but will not hold any public events.

Harper will campaign in British Columbia, and while it's not yet known what he will announce, it's all but certain the focus will again be the Mike Duffy trial.

Testimony in an Ottawa court on Thursday from Harper's former lawyer directly contradicted the version of events from the Conservative campaign — and they have not yet addressed the new information.

The Conservatives have said Ray Novak, Harper's current chief of staff, didn't know about then-chief of staff Nigel Wright's plan to repay Duffy's $90,000 in contested Senate expenses.

But Benjamin Perrin, who worked for a year inside the Prime Minister's Office, testified that Novak was present when Wright informed him of the repayment plan and was also present on a conference call during which Wright's payment was discussed.
