You’re presenting a new series called The Big Deal, where contestants are shown how to be art dealers. I absolutely hate any snobbery around art – who’s to say who is an artist and who isn’t? There’s a lot of personal things tied up in my dad’s art about growing up in a Catholic Irish family. My art teacher really rated my dad, so I didn’t like being compared to him! When he’s come to watch, I’ve heard him laugh – but not at me, only at Ian Hislop and Paul Merton.
