As a parliamentarian, I think I have the right to ask whether we may be wasting our time. The Conservatives, like anyone here, can move as many subamendments as they want. The subamendments can be new and constructive and have new content. We'll debate them; there's no problem with that.
I think that claiming to know where a colleague is going, implying that I'm filibustering, when I have spoken for three minutes out of around 20 hours of debate, is unfair.
I encourage my colleague, beneath his facade of fake kindness, to be careful about what he says when he talks about colleagues.
