Women embarking on the festive party season are being invited to stock up on free supplies of the morning-after pill.
The British Pregnancy Advisory Service (BPAS) has launched a service where women can request the pill over the phone and get it delivered free of charge to their home.
The charity says the move will help women prevent unwanted pregnancy over the Christmas and New Year period.
The morning-after pill is most effective if taken as soon as possible after unprotected sex, preferably within 12 hours.
But it can be taken for up to 72 hours after intercourse.
BPAS said women face barriers obtaining the pill, including not being able to get appointments, some health workers refusing to provide it and the £25 cost if bought direct from a pharmacist.
It says these issues are made worse at Christmas, when chemists and surgeries may be closed.
Women wishing to obtain the pill in advance can fill out a form at www.santacomes.org.
They leave their details and a time at which they can be called in privacy by a specially trained nurse.
In a 15-minute consultation, the nurse will assess the age of the patient and ensure the pill is not being requested for immediate use.
Women will also be told how to take the pill and what to expect.
The pill will then be despatched with condoms and “advice literature” to the woman’s home address.
