Tina Knowles, the mother of icons Beyoncé Knowles-Carter, Solange Knowles and bonus daughter Kelly Rowland, has just published her memoir Matriarch. It tells the story of how a resilient little girl, born in difficult times, became a powerhouse, guiding her daughters to their potential. How she, the great-granddaughter of two enslaved women, went from what she describes as a little, two-bedroom “poor house” with seven people in Galveston, Texas, to being the head of one of the most successful and high-profile families in the world. Ms Tina joins Nuala McGovern in the Woman’s Hour studio.

A new search has been launched in Portugal by police investigating the disappearance of Madeleine McCann. Madeleine was just three years old when she vanished while on holiday with her family in the resort of Praia da Luz in May 2007. Her disappearance sparked a Europe-wide police investigation and is one of the most high-profile unsolved missing person cases. German detectives are leading the search as they suspect she was murdered by a man who's currently in prison in Germany. BBC correspondent Daniel Sandford joins us from Praia da Luzh.

Northern Ireland doesn’t have a Mother and Baby unit to treat mums who are diagnosed with severe post-natal depression including post partum psychosis. Instead women are admitted to a General Psychiatric ward where they are separated from their babies. A BBC investigation has found that around 100 mums in Northern Ireland are admitted to a general psychiatric ward each year where they will be among other men and women who have a range of complex mental health issues. And these can be mixed wards. We hear from BBC’s Northern Ireland correspondent Marie-Louise Connolly who has made a Spotlight programme called Mums in Crisis and Dr Julie Anderson, consultant perinatal psychiatrist and Chair of the Royal College of Psychiatry in NI.

We know that there are structural barriers that women face to take the leap and start up a new business. Less than 2% of venture capital private investors funding goes to women only start-ups, according to Government figures. But Imperial College London are taking some big steps to address the barriers through a programme they run for women in the evenings called “WE Innovate” which gives women coaching and the practical skills and tools they need to figure out if their business idea has legs, how to pitch it to investors and how to develop it into a fully formed product. We’re joined by the head of the programme, Sarah Ranchev-Hale, and Dr Olivia Ahn, a success story of the programme who has invented the first certified flushable period pad which will be launched in shops soon.
