Hughes was 'never concerned for Arthur', says Ms Prior
Ms Prior continues: "Read the messages with care, she's regularly asking him 'please come back', 'please help', 'I can't cope', 'I'm crying', 'I'm broken', 'please take him back to his nan's'.
"She was saying again and again 'what do you want me to do with him?'."
Ms Prior says, in reply, Hughes told her to 'end him', 'finish him' and 'take his jaw off' but she did not do any of those things.
Ms Prior tells the court by May/June time Arthur had been headbuted, held and slammed up against a wall, grabbed by his arms, assaulted and had a foot placed on his stomach by Hughes, according to his own admissions in his interviews with police.
She mocks Hughes' notion Arthur had an ego aged six and says he crushed it by lying to Arthur he would be taken back to his nan's home, ripping up his football shirts and ignoring him.
Ms Prior argues Hughes was never concerned for Arthur and points to the fact on June 13 he texted Tustin trying to seduce at 5pm when the children were in the house.
"The noise, the cruelty was not stopping him getting an erection," she adds
