Last year the BBC Trust carried out its Children's Service Review. Part of my response was as follows -

Marrying Mum & Dad is a reality TV series in which children help to plan their parents' marriage or civil partnership. The first series, which did not include any civil partnerships, was transmitted last August. A second series was commissioned a few months afterwards - an insensitive and crass thing to do, with equal marriage rights so much in the spotlight.

CBBC has, it seems, now pulled tomorrow's scheduled 'civil partnership' episode of Marrying Mum and Dad, and replaced it with an episode from the first series.

I am still awaiting answers to my enquiries relating to the very early deadline which was imposed on applications to take part in the third series. Series 3 is being filmed at the moment.
