It is a controversial topic and one that may make for uncomfortable viewing.
BBC drama Call The Midwife is to tell the story of a pair of disabled lovers forced apart and ridiculed after the woman becomes pregnant.
Disability charities yesterday welcomed the plotline, saying it highlights how far society has come since the judgmental 1950s in which the programme is set.
The episode, which is to be aired on Sunday night, will feature the characters of Sally Harper, who has Down’s syndrome, and Jacob Milligan, who has cerebral palsy.
The pair live in an institution, having been sent there by their parents – as was common at the time.
But after they fall in love and Sally becomes pregnant, the couple are separated and Sally faces ridicule from her mother and father.
The episode deals with the prejudice and stigma she would have experienced.
Call The Midwife is shown on BBC One before the nine o’clock watershed, and in the past storylines featuring abortion, incest and infidelity have shocked viewers. But yesterday campaigners welcomed the inclusion of disability and love as a theme.
The character of Sally is played by Sarah Gordy, and Jacob by Colin Young. Both actors have the disability that they portray on screen.
