John Hogan, 33, from Bristol, is believed to have hurled Liam from the balcony then jumped himself with two-year-old Mia, in a suicidal act described as "selfish love" by his ex-wife, Natasha.

Liam died of head injuries but Hogan and Mia survived with broken limbs.

On the first day of evidence at the Criminal Courts of Chania, Crete, a jury panel heard how Hogan thought he was taking his children to "heaven" on the fatal night of August 15, 2006.

Standing in the same room as each other for the first time since the fatal fall, Hogan and Mrs Hogan, 35, clashed when he accused her of saying he was from a "family of death".

Mrs Hogan had broken down in tears as she described the night when Hogan gave her "a crazed look" before jumping from the balcony of the 227-bed four-star Petra Mare hotel, which overlooks the beach of Ierapetra.

Mrs Hogan said she booked the holiday in the hope of patching up their marriage, but instead it had been plagued by rows.

On the night of Liam's death, she got changed and took the children to the hotel's restaurant for dinner because Hogan was "agitated".

Before the death plunge, they had been rowing as she organised his suitcases, she said.

Describing their last words together, Mrs Hogan went on: "He said, 'My packing is crap. John's packing is crap'. I had my back to him and when I turned around no one was there."
