MH370 Pakatan Rakyat MPs are fuming over being left out of a Transport Ministry briefing on the MH370 crisis, scheduled for 8.30pm tomorrow at a hotel in Kuala Lumpur.

PKR’s Kuantan MP Fuziah Salleh (right) said the ministry’s invitation - extended only to BN representatives - belittles the parliamentary system and is disrespectful of Parliament itself.

She pointed out that acting Transport Minister Hishammuddin Hussein is a “minister for all Malaysians and not for BN alone”.

"We claim to follow the Westminster parliamentary system. But day by day, we are deviating from it," she said.

Fuziah called for a special closed-door Dewan Rakyat session to brief all parliamentarians on the on-going search and rescue operations for the Malaysian Airlines aircraft, which has been missing since March 8.

PKR’s Bayan Baru MP Sim Tze Tzin expressed shock that the invitation had been sent only to BN representatives.

The invitation letter, sighted by Malaysiakini and believed to be the one received by BN MPs, is dated March 14 and signed by Hishammuddin.

"(The disappearance of the aircraft) is a national tragedy and all MPs should be briefed thoroughly,” he said in a statement today.

"At this critical time, Hishammuddin ... is playing partisan politics, and we are sad and disappointed. Pakatan MPs are united with the rakyat in praying for (those on Flight) MH370. The onus is on the government to do the same now and walk the talk.”

However, BN’s Tanjong Karang MP Noh Omar defended the ministry’s decision, claiming that the opposition would have spread the information “on social media (even) before (the) briefing ends."

"Why are you questioning the minister's prerogative?" he asked.

Noh said Hishammuddin may table a White Paper on the matter “when the issue is settled”.

"Just be patient," he added, telling the opposition not to "spin" the story.
