A 35-year-old man has admitted pushing a cross-dressing top lawyer under a Tube train during the rush hour in London.
Solicitor David Burgess, 63, known as Sonia, died in October last year after falling in front of a train at King's Cross station.
Senthooran Kanagasingham, of Chichele Road, Cricklewood, north London, pleaded guilty to manslaughter on the basis of diminished responsibility.
But the prosecution at the Old Bailey refused to accept the plea and a jury was sworn to try him for murder, which he denies.
Kanagasingham had been undergoing sex change therapy at the time and used the name Nina. The shaven-headed defendant, wearing a shirt and grey jumper, claims he was suffering from paranoid schizophrenia at the time.
Brian Altman, QC, prosecuting, said: "Significant factors other than any abnormality of mental functioning were at play."
He said the prosecution's case was that the killing was "the very deliberate murder of Sonia Burgess".
Mr Altman said the killing was "born of anger and malice".
After shocked commuters saw Kanagasingham push Sonia Burgess on the back, a note found in Kanagasingham's rucksack said he was "broke, depressed and suffering from gender dysphoria".
