The partner of a Lottery winner has admitted trying to kill her at their home in Barry.
Stephen Gibbs was due to go on trial after he denied the attempted murder of Emma Brown in January.
But the 45 year-old changed his plea to guilty at Cardiff Crown Court. He will be sentenced next month.
Ms Brown was allegedly stabbed in the face, arms and stomach with a knife at her detached cottage in the Lakeside area.
The pair were believed to have been together for eleven years and previously owned another house in Barry, which was rented out.
Ms Brown (49) had quit her job at an aircraft handling firm around four years ago, after winning £5.5 million on the National Lottery.
She has made a full recovery since the attack
Judge Richard Twomlow told Gibbs that faces a ''lengthy prison sentence'' and the ''question of dangerousness'' had to be considered.
The hearing was adjourned to allow pre-sentencing and psychiatric reports to be prepared.
Gibbs was remanded in custody and is due to appear at Merthyr Crown Court on Friday 8th October.
