Prime Minister Stephen Harper's Conservatives have taken a wider lead over Michael Ignatieff's Liberals, a Leger Marketing poll released to the CBC suggests.

The Leger poll, conducted over the internet from April 27-29, gives Harper's Conservatives 36 per cent support among respondents, while the Liberals were at 25 per cent support.

It is the second poll in as many days that shows the Conservatives leading their Liberal opponents. A poll by research firm EKOS conducted exclusively for CBC News showed the Conservatives at 31.9 per cent support and the Liberals at 26.6 per cent.

The 11-percentage-point lead comes despite a difficult week for the Conservatives, who have been criticized for their handling of illegal lobbying allegations against former Tory MP Rahim Jaffer, as well as censured by the Speaker of the House of Commons over their refusal to hand over uncensored documents related to Afghan detainee transfers.

The New Democrats received 20 per cent support, while the Bloc Quebecois polled at nine per cent and the Greens at eight per cent, according to the Leger survey.

Unlike other polling firms, Leger includes the names of the party leaders in the voter intention questions alongside their party names, which the firm says reduces the number of undecided voters in the survey.  

"It puts things back in people's minds when they're not concentrating on politics," Christian Bourque, Leger's vice-president of research, told CBC News. "The emphasis on the leader is reflective of politics today."

Thirty-one per cent of respondents felt Harper would make the best prime minister, while NDP Leader Jack Layton came in second with 23 per cent support and Ignatieff a distant third at 16 per cent.

Despite Harper's personal numbers, 55 per cent of Canadians are dissatisfied with the Conservative government, including 25 per cent who consider themselves "very dissatisfied," the poll results said.

When asked whether Canada was heading in the right or wrong direction, 42 per cent of respondents said the wrong direction, while 37 per cent said the right.

The Leger poll sampled 1,505 respondents at random from Leger's panel of 315,000 Canadians. Because the survey relied on internet users, no margin of error could be reported — as a portion of the population cannot be reached with the medium.

To be representative of the Canadian population, Leger says its researchers weighted the data using the latest Statistics Canada information on gender, age, language and region.
