A Troon man who smothered his wife to death with a pillow has been cleared of murdering her.

Ian Gordon, 67, admitted killing his wife Patricia, 63, while suffering from diminished responsibility.

His plea was accepted after prosecutor Ian McSporran QC withdrew the charge of murder against Gordon at the High Court in Glasgow.

Jurors heard that but for the evidence of the couple's daughter Gail Whyte the murder trial would have continued.

Gordon, 67, killed his terminally ill wife Patricia at their home at North Drive, on April 28 last year by putting a pillow over her face.

Their daughter Gail, 46, previously described the long-standing ailments her mother suffered, her complete fear or hospitals and the incredible devotion her father had for her.

She also told the court she fully supports his actions.

On the third day of the trial, defence counsel Gordon Jackson QC resubmitted the plea to the lesser charge of culpable homicide.

Sentence was deferred and Gordon's bail was continued.
