I'm not a huge fan of hers - she was found out pretty quickly in the leadership elections - but she's someone who is popular with a lot of people I know who aren't hugely political.
Even so, Owen Jones isn't being genuine with his questions. He's looking for click bait responses, and you can see from his body language that he's not interested in finding out about Jess Phillips's views, he's decided what his view is of her before he starts and is mocking when she disagrees - not a good luck when he later shows that he doesn't actually know much about her.
That stuff about tax for people earning £80k is just weird. He says "where to start" when asked about what makes her right wing, yet can't actually name a policy that she's supported, or anything she's said. Instead he asks her to declare her support for specific tax rates that aren't Labour policy - something he knows no shadow minister would agree to. If he's so sure she's on the right of the party, and he's setting himself up as an expert, then he should know where to start, and be asking her to justify things she's said. What he's doing is not journalism, it's about the level of an amateur comedian on tiktok.
