Dr Lisa Cameron was the SNP MP for East Kilbride, Strathaven and Lesmahagow from 2015 until a week ago when she decided to join the Conservative Party. She has described the move as equivalent to leaving an abusive marriage. In her first radio interview since her defection, she joins Emma Barnett to discuss what led to her making this decision.

Listeners who have been through IVF treatment will be familiar the extra – and often very expensive – add-on services that many clinics recommend. The Human Fertilisation and Embryology Authority (HFEA), the fertility regulator, has now launched a ratings system to let patients see which add-ons are backed-up by evidence. Strikingly, not one of them has been given the highest "green" rating. Professor Tim Child chairs the HFEA's Scientific and Clinical Advances Advisory Committee. Jessica Hepburn spent over £70,000 on unsuccessful fertility procedures and now campaigns about the fertility industry. They joined Emma to discuss.

Three Little Birds is a new ITV series written by Lenny Henry which follows three women who emigrate from Jamaica to England in the 1950s - post-Windrush. The series is inspired by the stories of Lenny Henry’s family who, although had positive experiences of being helped as new arrivals, also shared accounts of physical and racial abuse when they reached the UK. Saffron Coomber who plays ‘Chantrelle’ and director Yero Timi Biu talk about the show.

Julia Fox is an actor, artist and fashion icon, as famous for her breakout role in the film Uncut Gems as she is for her spectacular avant-garde fashion choices. She became tabloid fodder after a brief relationship with Kanye West. Her memoir Down the Drain describes a troubled childhood of sex, drugs and abusive relationships in Italy and New York. She tells Emma how her high-fashion image allows her to escape the male gaze.
