Watching this now, and I think Rosie just made Graham's year:
Can I just say to Helen actually - she's saying that I've brought this to the world stage. It is incredibly important that people like me, who've come along now, acknowledge all of the things that you guys have done. Because you're incredibly... I mean, you know, all of the stuff that you've said and done has led me here and, sort of you know, you've walked through the streets on your own with a kind of torch going "look at me", and it's terrifying.
And it's scary for me in Parliament, kind of looking behind me and going "Oh my god, everyone hates me and no one's backing me up", but you guys were there first, and you taught me what was going on, and you were much braver. And Graham being completely, you know, obliterated by Twitter must have been pretty horrible.
By the look on his face, I think she's just secured a number one fan for life. 
(The cynic in me thinks that politicians are a bit too good at that sort of flattery + telling people what they want to hear, but I'm happy enough to see it directed at Helen+Graham+Arty).
