KUALA LUMPUR: Umno will take Tun Dr Mahathir Mohamad's newly-formed Gerakan Tanah Air seriously, says Datuk Seri Ahmad Maslan.

The party's secretary-general said Umno will not underestimate any opponent in the upcoming 15th General Election (GE15).

“Let them do what they want. What’s most important is that Umno and Barisan Nasional must be ready to face GE15, whenever it will be,” he told the media after Umno’s supreme council meeting on Thursday night (Aug 4) at the party's headquarters here.
