Thousands of people all across the country - and in London - are due to hold candle light vigils later this evening - in memory of Savita Halappananvar.
The 31 year old dentist died of blood poisoning last month in University College Hospital Galway after suffering a miscarriage - her husband says she was repeatedly refused a medical termination.
The HSE says it expects details of its inquiry into her death to be announced in a matter of days.
Protests will take place this evening in Dublin, Galway, Sligo, Killkenny and Carlow - all calling on the Government to legislate for the X Case, so that another woman in this country does not die in these circumstances.
A vigil will also be held outside the Irish embassy in London.
