Ralph & Katie

BBC One, 9pm & 9.30pm This big-hearted spin-off of Christopher Eccleston drama The A-word pivots around the lives of breakout characters Ralph (Leon Harrop) and Katie (Sarah Gordy), a married couple with Down’s syndrome, who are living as a couple for the first time. Premiering with a double-bill – with each episode by a neurodiverse writer – it is a charming, if saccharine romcom.
