Negotiating away a win

This doesn't exactly provide reason for confidence about the outcome of the ongoing negotiations on access to documents about torture in Afghanistan:

“We’ve crossed the Rubicon on the idea there’s a panel and the government crossed the Rubicon on the idea that they have to show un-redacted, unfiltered documents to MPs,” one MP familiar with the negotiations said.

“We’re circling around how the panel gets triggered and how do the MPs relate to the panel. That’s where we are, sort of,” the MP added.

Simply put, the supposed question as to whether MPs are entitled to "un-redacted, unfiltered documents" has already been definitely answered. And the fact that the Cons are finally acknowledging that reality can't be considered a concession.

Which isn't to say that it's completely unreasonable to work toward an agreed outcome with the Cons - as long as a separate panel process doesn't needlessly delay the release of documents, and the majority of elected MPs ultimately has the final say. But not coincidentally, it sounds like those are exactly the areas where the Cons are digging in their heels. And if that's the case, then the opposition parties should all stick to their current position of strength rather than bargaining away the notion of Parliamentary supremacy.
