The National Security has been tasked to conduct thorough investigations into the leakage of the 2015 Basic Education Certificate Examination question papers.
Deputy Education Minister, Alex Kyeremeh, said the investigation will be independent of what the West African Examination Council has begun doing.
Five papers including Mathematics 2, religious and moral education, English Language 2, and Science 2 have all been cancelled.
Social Studies will also not be taken tomorrow, whilst French and ICT will be written as scheduled.
The widespread leakage has left the country shocked as WEAC struggles to explain the circumstances under which the leakage occurred.
WAEC says it will not shield anybody found culpable for the scandal.
The Head of WAEC, Very Rev. Samuel Nii Nmai Ollennu told Joy News' Kwetey Nartey an investigation has begun to unravel how the papers were leaked.
But even before WAEC concludes its investigation, the Education Ministry has ordered a parallel investigation to be undertaken by national security.
Deputy Education Minister in charge of Basic Education Alex Kyeremeh said the ministry has given WAEC all the resources it needs and wondered why such a leakage would occur.
This is not the first time examination papers have been leaked in recent times.
Last year, a police officer at Atiwa, Lance Corporal Prince Opoku was indicted for breaking a seal on WAEC examination papers, taking photographs of the examination questions with his phone and subsequently leaking them to students.
He was allegedly contracted by a school proprietor to leak the papers and was paid 4,000 cedis for his work, the police report said.
One year on, the docket is yet to be sent to the Attorney General's department for prosecution.
Rev Ollenu had, prior to the 2015 leakage raised concerns about the failure of the police to prosecute the officer.
He is disappointed with the latest leakage, promising the Council will get to the bottom of the matter.
