I've had enough of life, I've had enough of this.' He adds: 'Stressing about little things.'

The couple met in 2011 when Joanne was on holiday in Egypt and Samak worked at a hotel Samak is seen crying as he speaks with police officers after stabbing his wife to death in 2024Samak said he was in shock and crying on the floor after the incident and when he finally called 999, the call handler told him to start CPR but he admitted he did not, despite being trained in the procedure and having a first aid kit in his bedroom.The court heard Joanne's blood was later found on clothing Samak had hidden in the loft.Joanne, who was the main breadwinner while Samak struggled to find a permanent job, suffered six stab wounds to the chest and abdomen, ranging between 2.5cm and 10cm deep.Medical experts told the jury considerable force was needed to penetrate her breastbone, making it highly unlikely she could have inflicted the injury on herself.Defending Samak, John Jones KC said he was a man of good character who had lost control and if there was an intention to kill, it was only momentary.But Judge James Burbidge KC said Samak's actions were 'wicked beyond comprehension' and he had destroyed the lives of his wife's family.Wiping away tears, Joanne's mother Penny Vale told the court her family and friends will 'never get over' the loss of the 'irreplaceable' interior designer, who was looking forward to starting a new job and celebrating her 50th birthday.Joanne's brother Mark Vale told the court his sister's death was 'unexpected, sudden, violent and immeasurably cruel'.The judge ordered Samak to serve a minimum of 21 years in prison, less the 483 days he had already served on remand, before a parole board will consider him for release.A jury in the first trial in February last year failed to reach a verdict.'Murder 24/7: Suicide or Murder' continues on BBC One at 9pm tonight
