KANGAR: The Malaysian Anti-Corruption Commission's (MACC) investigation into the Perlis menteri besar's son over false claims will not affect Perikatan Nasional's (PN) campaign for the Kuala Kubu Baharu by-election.

Pas secretary-general Datuk Seri Takiyuddin Hassan said late Pas leader Tan Sri Nik Abdul Aziz Nik Mat was also investigated by MACC in 2009 when he was Kelantan menteri besar over an umrah sponsorship involving a businessman.
