Hadhoud was the co-founder and board member of the Reform and Development Party.
The 48-year-old researcher died on 6 March while being held at the Abbasiya hospital, to which the prosecution said it had referred due to his "incomprehensible" speech during interrogation. He was arrested on 6 February after "attempting to breaking into an apartment in Zamalek," according to the interior ministry.
The request was submitted on Wednesday to House Speaker Hanafy El-Gebaly by MP Rawya Mokhtar, the representative of the parliamentary group of the Reform and Development Party.
According to the request, Mokhtar seeks to ask both Prime Minister Mostafa Madbouly and acting Health Minister Khaled Abdel-Ghaffar to "examine procedures in mental health hospitals [in Egypt] in general."
Mokhtar intends to ask whether "medical responsibility or administrative negligence" at the Abbasiya Mental Health Hospital had resulted in Hadhoud's death a month after his admission.
Hadhoud's death has "raised many question marks," Mokhtar pointed out in her request.
However, the prosecution said it was notified that he died of "a sharp drop in blood pressure and cardiac arrest."
The urgent statement will also call for the government to look into the treatment of psychiatric patients, including those in pre-detention, as well as care and services provided to them "due to the recurrence of similar incidents in mental health hospitals."
Mokhtar will demand the formation of a fact-finding committee to reveal patients' conditions at mental health hospitals.
The Reform and Development Party's request comes a day after the parliamentary bloc had issued a statement blaming the hospital for not notifying Hadhoud's family about his admission and denying his presence "more than once."
Hadhoud's death has stirred controversy over the past few days amid reports that he was the victim of "forced disappearance" -- a claim the interior ministry denied -- with his family reportedly saying it was notified about his death on 9 April, nearly one month after he died.
According to the public prosecution, preliminary examination of the body, conducted by the health ministry’s inspector and the police in March, showed no indication of "criminal suspicion" behind his death.
The prosecution added that investigation is ongoing and that it has ordered an autopsy to determine the cause of Hadhoud's death.
