Hashem Abedi is accused of 22 counts of murder and conspiring with his brother to cause explosions.

This isn't unexpected, his lawyers probably made him plead 'not guilty' so he gets to mount a defence challenging the wording of the charges on a semantic level, not to get him off but to stroke his own legal ego because lawyers are wanky sods.

Lawyers do this all the time, Saddam Hussian's lawyer had him plead not guilty despite his confession, argued the legality, location of the trial and the judges bias, even mounted an appeal. Before they hung the bastard like they were always going to do.
