Umno supreme council member Mohamed Nazri Abdul Aziz today unleashed a tirade on Chong Sin Woon after the MCA Youth leader told him to be a "real man" and apologise to tycoon Robert Kuok.

Nazri said Chong was not in a position to make demands until he proves himself against DAP national organising secretary Anthony Loke whom the tourism and culture minister described as a "good friend".

"This MCA Youth chief, he doesn't represent anybody. I hope he will challenge my good friend in Seremban, Anthony Loke.

"If he wins, he can then talk to me," he told Malaysiakini.
