"The Conservatives unveiled new radio spots in which they call on "all MPs" to get to work on the economy. It's an anti-coalition ad.

We've asked the Conservative Party what radio stations are playing this ad but they won't say.

Some of my more cynical colleagues suggest that the Party tells the Parliamentary Press Gallery that they're releasing these ads and then the media immediately puts them on their television or radio programs for free (as my old friends at CTV Newsnet just did).

So before I say any more about these ads, I'd like to know where they're playing. You can help: If hear one, tell me what the station is, the time, and what you thought of them."
