Umno Youth chief Khairy Jamaluddin said the wing's campaign for the upcoming twin by-elections will not be affected even if former prime minister Dr Mahathir Mohamad decides to go out on the stump against the BN.

"Whether he campaigns or not will not change Umno Youth's plans. We have our own plan and BN in general also has its own plan.

"We do not look at who will be fighting us or who will be campaigning against us, we only focus on our plans," he told a press conference at the Umno headquarters in Kuala Lumpur today.
