An advocacy group for families of victims of homicide is urging politicians to support a new bill which would introduce minimum sentences for those imprisoned for life.

Advic, which is holding a remembrance day today, says families are angered by the lack of clarity on how long murderers will actually serve for life sentences.

Hundreds of families attended a service in the Freemasons Hall in Dublin this afternoon where victims of murder and manslaughter where remembered.

Barbara Clinton, Advic chairperson, said: "Every time we gather for our remembrance day, it is a stark reminder that families are the only people who are forced to serve life sentences."

Ms Clinton called on politicians to support a private members bill being introduced by Senator Marie-Louise O'Donnell in the Seanad.

The Bill is modelled on legislation already operating in England and Wales where prisoners serving a life sentence are eligible for parole after a fixed minimum period or a tariff.
