Key factors contributing to the irregularities flagged in the Comptroller and Auditor General (CAG) reports may include: 1. Lack of transparency: Irregularities can arise when there is a lack of transparency in government processes, contracting, and financial management. 2. Inadequate oversight: Insufficient oversight mechanisms and weak internal controls can lead to irregularities going unnoticed or unaddressed. 3. Corruption: Corrupt practices such as bribery, embezzlement, and favoritism can contribute to irregularities highlighted in CAG reports. 4. Inefficiency and mismanagement: Poor planning, improper budgetary allocation, and mismanagement of resources can result in irregularities. Regarding the Prime Minister's response, it is important to note that while the CAG reports identify irregularities, it is not the role of the Prime Minister to directly investigate or comment on specific cases flagged in these reports. The responsibility primarily lies with the relevant government departments and investigative agencies to address the irregularities uncovered. The Prime Minister's silence could be due to the fact that ongoing investigations or actions are being carried out by the appropriate authorities to address the highlighted issues.
