The lawyer for John Hogan, accused of murdering his six-year-old son Liam on a family holiday in Crete, is preparing this week to have a psychiatrist examine him in an attempt to prove that he was mentally not responsible for his actions.

The 32-year-old businessman from Bristol, who jumped 50ft from a hotel balcony with his son and two-year-old daughter Mia, is in a Greek prison psychiatric unit on suicide watch after he slashed his wrists. Both of his brothers, Stephen and Paul, committed suicide.

British consulate staff are visiting Mr Hogan in the maximum-security Korydallos prison in Athens. He faces a wait of up to 18 months before he is put on trial for the murder of Liam and attempted murder of Mia.Mr Hogan sustained a broken arm, and leg and chest injuries in jumping from the hotel balcony in Crete. Liam died from head injuries and his sister had a broken arm.

Liam's funeral was held last week in Bradley Stoke, Bristol, near the family home. An inquest has been opened and adjourned.
