The Catholic Bishops Conference of England and Wales have joined the protest against plans to advertise abortion services on television.
A spokesperson for the CBCEW said: "We believe that services which offer or refer for abortion - whether commercial or not-for-profit organisations - should not be allowed to advertise on broadcast media.
"Abortion is not a consumer service. To present it as such erodes respect for life and is highly misleading and damaging to women, who may feel pressured into making a quick decision, which can never be revoked. Moreover, to allow the broadcasting advertising of abortion-referral services is, in effect, to allow the exploitative promotion of these services and is not in the interests of the health or psychological well-being of women.
"For this reason the Bishops' Conference of England and Wales has consistently opposed any relaxation of the BCAP Guidance on broadcast advertising to allow this.
"The Bishops of England and Wales encourage and support women to make informed choices about their emotional, psychological and physical well-being. The Bishops support a number of charities which do this, in particular the organisation called 'LIFE' which offers confidential information, counselling and practical help and support for women contemplating abortion, suffering after pregnancy loss or struggling to cope after abortion."
