Channel 4 is heading back to Lancashire as Britain’s “biggest family under one roof” continues to expand.

18 Kids and Counting (working title) is an hour-long programme made by Lion Television.

Viewers return to Morecambe as they welcome baby girl Hallie into the clan. Her arrival coincides with the wedding of sister, Sophie, who has to organise 17 siblings as bridesmaids and page boys.

The programme will also film in Scotland and the Hann family, who have 13 children, who like the Radfords all live in the same house.

It was commissioned by Ian Dunkley and is due for transmission later this year.
