Chief Minister O Ibobi Singh administered the oath of office and secrecy to the newly-sworn in parliamentary secretaries at a simple function at his office.
The parliamentary secretaries are K Meghachandra, M Prithiviraj, Victor Keishing, Vungzagin Valte and Md Amin Shah.
Senior cabinet ministers and senior civil and police officials were present during the function.
Official sources said all the five parliamentary secretaries would be given the charge of government deparments like the minister of state of state and will have all the facilities given to the minister of state.
Political observers said the swearing in of parliamentary secretaries followed because of discontentment amongst Congress MLAs who could not get ministerial berths.
As per provisions of the constitution under Anti-Defection Law, Manipur with 60 MLAs can have only 12 ministers.
The present strength of the assembly is - Congress 42, Trinamool Congress 7, National People's Front 4, Manipur State Congress Party 5, Lok Jana Sakti Party 1, and National Congress Party 1.
