MICHELLE Mone, the former lingerie tycoon and Iain Duncan Smith’s start-up tsar, will discuss dating in the 21st century when you’re over 40 when she guest edits BBC Radio 4’s iconic Women’s Hour later this month.

The soon-to-be Lady Mone will also lead discussions about the psychology of weight loss and will look at the barriers to employment and business opportunities in deprived areas, the power of mentoring, how the mind, body and career are all linked, and what it means to be a good employee.

The topics are all subjects close to her heart. She once shed six stones, claiming to have used her own diet pills. In a controversial move, she was recently appointed as the Government’s start-up tsar to lead a review looking into ways to support new business start-ups with high unemployment.

Mone, 43, is thought to have a personal fortune in excess of £20 million – from lucrative mentoring schemes and speaking engagements for which she charges up to £20,000 a time.

Her company MJM International – which employed just 42 people in the UK – suffered losses of £780,000 in 2013 and parent company Ultimo Brands also made a loss. She has since sold 80 per cent of the business.

Mone is also back on the dating market, after a protracted divorce from her husband and former business partner Michael Mone after she accused him of having an affair.
