Natasha Visser was commenting after a coroner delivered a verdict of unlawful killing on her son Liam Hogan.

Liam, from Bristol, died of severe head injuries after falling 50ft from the Petra Mare Hotel, in Crete, with his father, John, and sister, Mia, then aged two.

John Hogan, 33, was cleared of murder earlier this year after a Greek court heard he was suffering an "earthquake" of psychosis when he took Liam's life.

But, after Avon Coroner Paul Forrest concluded Liam's inquest by saying his death was unlawful, Mrs Visser, 35, said: "Justice has so far not been done."

A spokeswoman for the Crown Prosecution Service said it would consider any evidence sent by the police.

Mrs Visser, speaking at the end of the inquest in Bristol, criticised the Greek proceedings.

The inquest heard from eyewitnesses who saw Hogan push the children from the balcony but were not called to give evidence during the trial in Crete.

Mrs Visser said the inquest verdict "comes as no surprise, and in the light of this new body of evidence we understand that it will now be up the English Crown Prosecution Service to consider very carefully what, if any, action they will take for the prosecution of John Hogan for murder and attempted murder in the UK as justice has so far not been done."

She added: "The Greek court made little attempt to establish the facts surrounding Liam's death and did not even call known eyewitnesses."
