No conspiracy theories, just basic democracy and parliamentary privilege!
And I would argue that after John McDonnel's (Shadow Chancellor) defence of Corbyn's reshuffle, democracy is certainly on the wain in the opposition. The justification given to Radio 4, at 0810 this morning, was that to remain on the front benches you can't openly disagree with Corbyn in the HoP. The 'so what' for Defence and the country, is that we now have an opposition leader and his shadow Defence Minister that are quite determined not to see the nuclear deterrent replaced. It was even stated that if there were to be any further 'free votes' the front benches would have to toe the party line. A sad day!
