A former air force major, who was sacked for disclosing classified military information in Malaysia, will be a key witness in a lawsuit against the Malaysian government and Malaysia Airlines next week over the disappearance of flight MH370.

Zaidi Ahmad, a former Royal Malaysian Air Force officer, was dismissed from the armed forces after being found guilty of leaking confidential information without consent about indelible ink used in the election in May 2013.

Ahmad is making headlines again by wanting to help the families of the victims of flight MH370, which disappeared without trace on 8 March last year.

He believes "heads must roll" after the military failed to act when the flight re-entered Malaysian airspace. His evidence will be taken into account as a former member of the Royal Malaysian Air Force (RMAF).

He will be one of five witnesses to appear at Kuala Lumpur High Court on Tuesday (17 January) on behalf of a lawsuit filed by two sons whose father was on board the doomed flight.

"I believe it shouldn't have happened, [the RMAF] should be on alert all the time.

"Heads must roll," Ahmad told MalayMailOnline.

But the Malaysian government's stance remains that no action was taken to pursue the aircraft because it was considered non-hostile.

A massive search covering a 60,000 sq km area in the Indian Ocean is currently underway in the southern Indian Ocean where it is believed the Boeing 777 is lying after it veered off its flight path towards Beijing.

Families of the 239 victims are not satisfied with the authorities' formal announcement last month declaring that the tragedy was an "accident" and are in pursuit of the truth and justice.

Ahmad used to be positioned at the RMAF Butterworth airbase which the plane flew over after it changed course and then vanished from radar. The Malaysian air force has come under criticism for failing to act after detecting the plane.

"The most important thing is that this involves the government's assets and as a Malaysian citizen, I am concerned especially with the readiness of the armed forces as a whole in handling any intrusion into our air space," Ahmad said.

Datuk Dr Arunan Selvaraj, the lawyer representing the two sons against the Malaysian government and Malaysia Airlines at the case management hearing next week, said: "The monetary gain is one thing, but our clients also want justice. They want people to be accountable.

"This is one of the ways we can get to know what transpired."
