@Freddo - I also like Portillo.
I didn't like him when he was an MP - Portillo himself has said that his younger self was a "tyke" who has "mellowed" over the years.
But I do like him since he's been a political pundit. A lot of what he says makes sense and he makes his often moderate points in a sensible, polite fashion.
I also like This Week. Compared to other political discussion shows, it's very 'cosy'. There's usually a good chemistry between Andrew Neil, Portillo and Abbott (and latterly Alan Johnson, Liz Kendall).
If you look at the vid in the OP, Portillo and Neil are laughing at Diane Abbott but there's no nastiness. It's all done good-naturedly.
Meanwhile, Diane Abbott's the gift that keeps giving!
