Tempers flared when some 100 Umno Youth members confronted a Parti Pribumi Bersatu Malaysia (Bersatu) Youth wing delegation at the Putra World Trade Centre (PWTC) in Kuala Lumpur this afternoon.

The Bersatu Youth delegation wanted to submit an invitation to Prime Minister Najib Abdul Razak to attend the "Nothing to Hide 2.0" forum to debate with their chairperson Dr Mahathir Mohamad.
