Comedian Frank Skinner is to defend priestly celibacy alongside a Catholic bishop in a debate two days before the Pope’s visit.
Mr Skinner, a practising Catholic, will argue that celibacy should continue to be a requirement for Catholic priests.
He will be joined by Jack Valero, a spokesman for Opus Dei and for the Cause of Cardinal Newman, Fr Stephen Wang, dean of studies at Allen Hall seminary, and Bishop Malcolm McMahon of Nottingham.
They will be debating against theologian Tina Beattie,
human rights lawyer Helena Kennedy and Carmelite Fr John McGowan.
The event takes place at the Odeon cinema in Leicester Square and will follow a screening of Conspiracy of Silence, a controversial film about a priest who wishes to marry.
The debate will also be broadcast on BBC Radio 4.
The list of speakers engaged in it promise to be high quality.
