70-year old twin prostitutes says they slept with 355,000 men during their 50-year career in Amsterdam red light district

Identical twins Louise and Martine Fokkens shot to fame earlier this year as stars of a documentary charting their 50 year careers as prostitutes in Amsterdam.

Now the 70-year-old Dutch sisters are celebrating their retirement with a tell-all book about their lives and the industry, and today they admitted to This Morning hosts Holly Willoughby and Phillip Schofield that they have entertained 355,000 men between them.

Louise revealed that her bad arthritis meant that she had retired from prostitution two years ago causing the telly hosts to exclaim: 'No wonder you have arthritis. You must have very flexible hips!'

Louise, who became a prostitute aged twenty after a brief spell making lampshades explained how she got in to the business:

'We didn't have enough money.

'My husband's friends said it was the best way to make money so we decided to find out. I was 20/21 the first time.

'At first it was a problem for our mother and father but later we all lived normally with it.'

Martine, a mother-of-three who still works as a prostitute two to three times a week said:

'My family told me about my sister while I was in the hospital having my first baby.

'I didn't believe it but we talked about it and I loved her, that's life.'

Martine then started working at the brothel as a cleaner but two years later decided to join her sister as a prostitute after so many clients mistook her for her identical twin.

'I helped her with her first client: told her what she had to do and what she shouldn't do.'

Louise, who has four children and nine grandchildren said: 'I helped her with the first client: told her what she had to do, what she shouldn't do.'

Unsurprisingly the women are familiar faces around the red light district, and over their five decades working in the sex industry freed themselves from the control of their pimps, ran their own brothel, and set up the first informal trade union for prostitutes.

The women continue to be shocked at how different the industry is now to how it was in the 1960s when they first started out.

Louise said: 'It is very different now. We used to sit in the windows with clothes on, today they are totally naked.

'We have written about our life for over 50 years in the industry. It is our side of the story.'
