The Question Time host has previously said she hates it when she's at a party and no one's dancing, so much so that she wouldn't consider her drinks and dinner parties at home a success, until her guests let loose.

"She stopped working when she had her first child and never went back," Fiona told Radio Times. "My parents' set-up was very traditional. I do judge my parenting skills against hers and often find myself falling short. She was always there, but I'm not."
"We have had the same nanny for 20 years and that has made so much of my working life possible," she added. "But I do have a fair dose of working mother's guilt. Would it have been better for my children had I been at home all the time? I don't know. I've asked and they say no!"
