Hassan Mustafa, 35, formerly of Stratford Road, Sparkbrook, denies a charge of murder. The jury will be asked to consider a verdict of not guilty by reason of insanity.
The defendant and Mr Yousef were Sudanese nationals who sought asylum in the UK five years ago.
Mustafa was armed with four knives.
The BBC now routinely buries these stories on 'regional' news pages.
They would much rather report on 'racist' cartoons of Serena Williams.
Fuck the BBC
