Compass' idea of debate

Neal Lawson's fan club Compass have an interesting idea of what constitutes debate.

Tonight they have a "debate" (their description) at the Commons on Trident replacement.

The speakers are:

Charles Clarke MP - sceptical about replacement
Jon Trickett MP - anti-replacement
The Rt Rev Dr Thomas Butler, The Bishop of Southwark - anti-replacement but more famous for his enjoyment of Irish embassy receptions
Bianca Jagger - not previously known as an expert on nuclear weapons but presumably anti
Gemma Tumelty, (President of the NUS) - ditto
Kate Hudson of CND - anti
John Sauven, the Executive Director of Greenpeace UK - anti

Very balanced!

As Des Browne and his ministerial team at MoD have been very happy to engage in debates on this - I saw Browne speak at the balanced 2 speakers per side debate that Progress held - why isn't there a single pro-replacement speaker on the platform?

Are Compass scared that their arguments might not stand up to public scrutiny and real debate?

Is their own stitched-up non-debate an example of the kind of pluralistic, democratic Labour Party they want to bring about?
