Our NDP (left wing) party leader has been very vocal about releasing it too. It's been suspected that both left/right parties are on the list but only the Liberals are vocally against releasing it (also Greens seem to be against it too). The Liberals probably think they have the most to lose since they are already getting completely destroyed in the polls and don't need another thing, but the mystery of not knowing and Steisand effect is just as bad, so the decline will surely continue.

I believe i have heard they were from numerous parties? I Believe the CPC was implicated as well?

The article says otherwise.

> But surely the Opposition will raise hell? Don’t count on it. On the day after the committee’s report was released, the Conservatives asked 24 questions in Question Period. Not one was about the report, or its allegations. (On Wednesday, Conservative Leader Pierre Poilievre called on the government to release the names – after it had become clear it wouldn’t.) Possibly this might reflect a suspicion that some of its own partisans might be involved. Didn’t the committee say it had seen “considerable evidence that Parliamentarians across all parties and groups are potential targets for interference activities”?

> Doesn’t its report also note – again confirming previous media reports – that two recent Conservative leadership races have been subject to interference by China, and one by India?

> Here again, however, we are likely to face an all-party conspiracy of silence. None of the parties has shown the slightest willingness to have its internal elections vetted by independent regulators – just as none is likely to be too keen to look into what some of its MPs might have been up to. In time, they may hope, the public will get bored, and the media will move on. And in this regard they are probably right.
