Opposition leader Anwar Ibrahim and former prime minister Najib Abdul Razak will be facing off against each other in a much-awaited debate session that will be televised and streamed live tonight.

The event is scheduled to start at 9pm at the Malaysia Tourism Centre (Matic) in Kuala Lumpur where the PKR president and Umno leader will debate two topics - whether the government should assist ailing oil-and-gas company Sapura Energy Bhd and the issue of Malaysia's future in terms of its economy, politics and direction.
