By Sky News SkyNews - 17 minutes agoA woman has been jailed for 30 years for poisoning her husband's curry with anti-freeze.

Kate Knight's plot began as the "idle musings of a bored and lonely housewife" and left her husband Lee blind and deaf and suffering from brain damage.

She wept as Judge Simon Tonking told her she would serve at least 15 years in prison before she is eligible for parole.

He said the offence contained "premeditated planning of a most callous kind".

The public gallery cheered and clapped as he read out his sentence.

Knight, who was found guilty of attempted murder last month at Stafford Crown Court, was hoping to get her hands on her husband's life insurance.

She wanted to use it to pay off mounting debts, thought to be around £17,000.

The 28-year-old used ethylene glycol to poison an Indian takeaway he ate on their seventh wedding anniversary.

She had used Google to research the best method to kill him, first considering hiring a hitman, and then deciding on anti-freeze.

But she was found out when she confided in a neighbour about her plan.

The court heard Knight was "living in a world of fantasy" and her idea to kill began as "idle musings of a bored and lonely housewife" which eventually became a reality.

Judge Tonking told her: "Your first thought about killing your husband may well have been born out of fantasy which then drifted into a reality."

But he said: "You were fully responsible for putting it into effect and for its consequences."

Mr Knight, who worked at the JCB plant in Uttoxeter, Staffordshire, recently underwent an operation to restore some of his hearing.

But the 37-year-old still required two hearing aids and support from two specialists to give evidence at his wife's trial.

He said his wife "had ruined his life".
