A new CTV poll shows the Wildrose party is still leading the provincial election campaign, but leader Danielle Smith's approval rating has slipped slightly.

According to the ThinkHQ survey, Smith's approval rating has been steadily climbing since last December, from 40 per cent to 56 per cent last week.

But that slipped a bit to 54 per cent this last week.

PC leader Alison Redford's approval has been steadily declining, from 59 per cent in December to 46 per cent this last week.

Albertans were also polled about a PC re-election.

A solid 50 per cent say the Tories do not deserve to continue to lead this province.

23 per cent thought they should be re-elected and 27 per cent are still not sure.

And if an election were held tomorrow, which parties' candidate would get your support?

The Wildrose holds onto a solid lead at 43 per cent, followed by the PC party with 29 per cent.

"There has been very little movement with the parties, very little movement in terms of leader evaluations. All the changes from this week to last have been extremely subtle, all within the margin of errors, which is a bit surprising given that it was full up campaign week last week," says ThinkHQ's Marc Henry.

13 per cent of Albertans would vote for the NDP, 12 per cent for the Liberals, the Alberta party would get 2 per cent of the vote and 1 per cent would vote for other.

Albertans will head to the polls April 23.
