Incarcerated Mandevu MP Jean Kapata and her Munali counterpart, Mumbi Phiri have been admitted to the University Teaching Hospital (UTH).
But police spokesperson Bonnie Kapeso has maintained that the two will not be given police bond but will have to appear in court on Monday.
Meanwhile, the Civil society organisations spearheading the honking against Fredrick Chiluba have increased the time to honk and whistle.
The two MPs are said to be treated for high blood pressure as Jean Kapata has reportedly collapsed at the police cells.
Police spokesperson Kapeso said that the two, with other arrested protesters, were Friday formally charged with conduct likely to breach public peace and unnecessary hooting contrary to the Laws of Zambia.
He said this charge does not merit paying admission of guilty fee at the police station and be released but requires going to court.
On the extended time of hooting, civil society spokesperson Samuel Mulafulafu says the the hooting will now be for 24 hours every day.
He said the police will have to create more space in cells to detain all the protesters.
