A jealous boyfriend was jailed for trying to murder his £5.5million lottery winner partner after accusing her of having a secret affair.
Stephen Gibbs, 45, used a kitchen knife to stab Emma Brown seven times in the face leaving her in a pool of blood on the patio of their luxury home.
The couple had been happy for eight years but when Emma, 49, won the lottery in 2017 their relationship changed the next day, a court heard.
Gibbs wiped away a tear as partly-blinded Emma told the court she had once loved him but now felt nothing but pity.
He was given an 18-year extended prison sentence after admitting attempting to murder his millionaire girlfriend.
Flooring contractor Gibbs turned down Emma's dreams of travelling the world on her winnings and instead became possessive, controlling and jealous.

'He was jealous and worried about her past and there was a mention of Macca, which was Mr McKenzie's nickname.
'He said: 'I don't believe you - you have been to see Macca.'
When former airport worker Emma told Gibbs she wanted to break off their 12-year relationship he grabbed her around the neck, slammed her against the wall breaking her arm and went to the kitchen to grab a nine-inch kitchen knife.
Mr Bennett said: 'He told her he was going to cut his own throat and she was trying to stop him when he turned his anger on her, still holding the knife.
