Media statement: Daily Mail report of Marie Stopes UK

Paul McPartlan, Managing Director at Marie Stopes UK, said:

“We do not agree with the conclusions this journalist has reached, which give a seriously misleading view of how our services operate. No reporter in this investigation went through the legal admission process that women must go through before receiving an abortion, so their claims are based on a partial view of the process.

“Following last year’s CQC inspections of our services, we took the concerns raised very seriously. Since then, we have worked extensively to address these concerns and make ongoing improvements. We continue to work closely with the CQC, who are monitoring our clinics and head office to ensure the improvements we have made meet their expectations and are being embedded.

“The process by which women access our services adheres fully to the Abortion Act and the Department of Health’s Required Standard Operating Procedures and is monitored by the Department of Health and CQC. No abortion is carried out in our clinics unless two doctors are satisfied that the legal requirements have been fulfilled, the woman has understood her treatment and consented to the procedure during a face to face appointment with a registered nurse, and there are no medical reasons why it shouldn’t proceed.

“The CQC rightly praised our helpline, which is the first point of contact for the thousands of women who rely on our services each year. To suggest that our helpline staff are not appropriately trained to do their jobs is both incorrect, and contradicted by CQC’s own report into the service.

“We are proud of the improvements we’ve made since our CQC inspections last year, and we recognise that there will always be more to do. However, irresponsible journalism like this needlessly worries women in need of abortion services, and undermines the efforts of organisations like ours to deliver a high-quality service. We have sought legal advice and will be exploring appropriate legal action.”
