Tun Dr Mahathir Mohamad says he has no opinion over Datuk Seri Anwar Ibrahim's move to contest in the Port Dickson parliamentary seat. 

The Prime Minister said the PKR-president elect rang him up from Hong Kong to inform him about contesting in the seat before the announcement was made.

During a press conference on Friday, Dr Mahathir said he told Anwar that he normally does not go on any campaigns for by-election, but will endorse Anwar’s candidacy.
