Support for the Liberals has fallen to its lowest level since the last weeks of the June election, finds a new poll that was conducted just as action at the Gomery inquiry was heating up.

The Ipsos-Reid poll for CTV and The Globe and Mail was conducted on the two days before April 7 -- the day the publication ban on testimony heard at the Gomery inquiry was lifted -- and then again that night.

The survey found that if an election were held tomorrow, 34 per cent of decided voters would vote for the Liberals, down three percentage points since February 2005, when Ipsos-Reid conducted its last poll.

Thirty per cent would vote for the Conservative Party and 15 per cent would vote for the NDP.

In the June 28, 2004 election, Liberals received about 37 per cent of the popular vote, while Conservatives took about 30 per cent and the NDP about 16 per cent.

Within Quebec, the new poll found the Bloc Quebecois would get 41 per cent of the decided vote, compared to just 29 per cent for the Liberals. For the Liberals, that's a five-percentage-point drop from February.

Nationally, the Bloc would get 10 per cent of the decided vote.

Of the remaining voters, seven per cent would vote for the Green Party, and four per cent would choose "Other." Eleven per cent of respondents said they "don't know" who they would vote for.

With new corruption allegations heard at the sponsorship inquiry, it remains to be seen if those poll numbers will change.

The greatest shift regionally was seen in Alberta. There, the Conservative Party has seen a 14 percentage point shift in its popularity, to 57 per cent, while the Liberals have seen a 16-point drop, to just 13 per cent.

But in Saskatchewan/ Manitoba, the Liberals have gained 12 points of support, to 36 per cent, while the NDP have lost 14 points to 11 per cent.

In the Liberal stronghold of Ontario, where Conservatives would need to gain seats in order to form a government, the gap has narrowed. The Conservative Party has picked up six points and has climbed to 34 per cent of the decided vote, while the Liberal Party has dropped five points and now sits at 38 per cent.

The telephone survey of 1,000 Canadians was conducted between April 5 and April 7, 2005. Results are considered accurate to within +/- 3.1 percentage points, 19 times out of 20.
