The recently-concluded Semenyih by-election recorded the highest number of electoral offences than the previous five by-elections conducted since GE14, said Bersih today.The electoral reform group's chairperson Thomas Fann told a press conference that the highest number of offences was committed by Pakatan Harapan (21), followed by BN (13), and one by an unknown party."We are disappointed that despite efforts to highlight election offences by the Election Commission (EC) and Bersih, there are still political parties breaking the law."Is this because they think no action will be taken against them even if they break the law?" he told reporters at the Bersih headquarters in Petaling Jaya.
