BBC News, Derby, 20 November 2019: The family of a woman jailed for a plot to poison a prime minister has lodged an application to review her case.
Alice Wheeldon was convicted in 1917 of a conspiracy to kill David Lloyd George as she opposed World War One.
The shopkeeper, from Derby, and her children had become the focus of government attention.
A family descendant said "documents suppressed by the state" show the trial was unfair and that her trial should be quashed.
Wheeldon, her daughter Winnie Mason and son-in-law Alfred Mason were all convicted of conspiracy to murder.
She had become the focus of government attention because she was a suffragist and an anti-war activist.
A man called Alex Gordon pretended to sympathise with them, but he was an MI5 spy who claimed they were plotting to kill Lloyd George with a poisoned dart.
Wheeldon's great-granddaughter Chloe Mason, who lives in Australia, came to England to deliver the application to the Criminal Cases Review Commission.
She said: "I am absolutely delighted and relieved it's come to this day."
