Now, four ex-military personnel have confessed to committing election fraud - the same way an ex-army man said he did so earlier this month.
The four, who had served at army and air force bases across the country, say they marked thousands of postal votes in three separate general elections between 1978 and 1999.
The four - Major (Rtd) Risman Mastor (right), Kamarulzaman Ibrahim, Mohamed Nasir Ahmad and Mohd Kamil Omar - said they were ordered by their commanding officers to mark postal votes for the hundreds and thousands of personnel who were out in the field.
Their expose today is the second after an ex-army man came forward earlier this month, making a similar claim that he was ordered to mark postal votes for other personnel.
