Weekend Woman’s Hour: Royal Navy exclusive, Tamsin Greig, Period Tracker Apps, Formula One, Sleepwalking, Choral music

A female officer in the military says she was raped by a senior officer who was responsible in the Royal Navy for behaviours and values, including sexual consent. Speaking exclusively to Woman’s Hour, the female officer, who we are calling Joanna, reported the incident and her allegations to the military police who brought charges against the officer. However, the Services Prosecution Authority later said that they wouldn’t be taking the case forward to a military court. The female officer, who feels she has been forced to leave the military, says that her career has been left in ruins, whilst his continues. The Royal Navy has said “sexual assault and other sexual offences are not tolerated in the Royal Navy and anything which falls short of the highest of standards is totally unacceptable" and that since the alleged incident they "have made significant changes to how incidents are reported and investigated." Nuala spoke to Joanna and the Conservative MP and member of the Defence Select Committee, Sarah Atherton.

Period tracker apps claim to help women to predict when they might start their period and calculate the best time to attempt to conceive. The Information Commissioner's Office has said that a third of women have used one. A report out this week, however, has raised serious questions about the way in which this data is used. The study, by Kings College London and University College London, examined the privacy policies and data safety labels of 20 of the most popular of these kind of apps. Anita discusses the findings and implications with BBC Technology Reporter Shiona McCallum and the lead author of the study Dr Ruba Abu-Salma from Kings College London.

Known for her dramatic and comedic roles on TV, stage and film the Olivier award-winning actor Tamsin Greig is currently performing in The Deep Blue Sea - Terence Rattigan’s 1950’s study of obsession and the destructive power of love - at the Theatre Royal Bath. She joined Nuala to explain the appeal of her latest role and why in 1952 legendary actor Peggy Ashcroft said she felt she had no clothes on when playing this part.

Talking about her new book, 'How To Win A Grand Prix', Formula One expert Bernie Collins takes Anita behind the scenes of an F1 team, and explains how she forged a career working as a performance engineer at McLaren for names such as Jenson Button, then became Head of Strategy at Aston Martin, with world champion Sebastian Vettel.

Journalist Decca Aitkenhead regularly sleepwalks. She talked to Nuala about her night-time escapades which include finding herself locked out in the middle of the night, eating food she’d find disgusting when awake and incredible strength that has seen her smash furniture to pieces. She’s joined by neurologist and sleep expert Prof Guy Leschziner who explains what’s going on in our brains when we sleepwalk, and how women are affected.

How has the role of women in choral music changed? With girls as well as boys now singing in cathedral choirs and more music by female composers being commissioned and performed, women’s voices are becoming increasingly prominent. Composer Cecilia McDowell and singer Carris Jones talk about championing and celebrating women in this traditionally male world.
