Former Selangor Umno liaison chief Dr Mohd Khir Toyo believes that the repeated attacks on PKR Hulu Selangor by-election candidate Zaid Ibrahim’s past as a drinker was a good campaign strategy.

The move to highlight Zaid’s admission that he used to consumed alcohol in his younger days was a way to discourage PAS’ grassroots from supporting the former minister, said Khir.
