Tan Sri Muhyiddin said the 2.2 billion ringgit Kinrara-Damansara Expressway or KIDEX highway contract, was awarded to the most qualified companies.
He also dismissed allegations that the deal was given to companies linked to Umno lawyer Datuk Hafarizam Harun, and the wife of former Chief Justice Tun Zaki Azmi, based on political reasons.
The deputy premier said the project was awarded based on proper evaluation and submissions submitted by the company.
The companies in question are Emrail Sdn Bhd and Zabima Engineering Sdn Bhd
Datuk Hafarizam is a director in both firms while Tun Zaki's wife, Toh Puan Nik Sazlina Mohd Zain is Emrail's director.
