Is it Winifred Robinson? If so she is AWFUL.Whoever is hosting You and Yours is annoying me - just let people speak!!! No one wants to hear you interrupting every five seconds to react or cut people off
As you say interrupts constantly, chips in with irrelevant nonsense so the interviewee stops to say 'pardon?' and looses their train of thought so it becomes so awkward and they start speaking over each other.
The other thing she does is have an awful inappropriate laugh eg 'my house was broken into last month' 'giggle giggle oh no that sounds terrible'.
She's unlistenable these days tbh.
