A Salford man is on trial accused of murdering Indian student Anuj Bidve on Boxing Day.
Kiaran Stapleton, 21, admitted to killing Mr Bidve, 23, in a preliminary hearing but denied murder after the university student was shot from point-blank range.
The defendant is claiming manslaughter on the ground of diminished responsibility but it was rejected by the Crown Prosecution Service.
Mr Bidve’s parents, Subhash and Yogini, are expected to be at the trial after flying fly from their home in Pune, India.
Their son arrived in England in September 2011 and was studying for a micro-electronics postgraduate qualification at Lancaster University.
He was travelling with friends through Ordsall to the Boxing Day sales in Manchester city centre when he was killed.
The trial before Mr Justice King at Manchester Crown Court is expected to last up to 12 days.
