According to the aide, those affected include director of protocol, Arthur Ndiwe and the head of administration, Mrs Folasade Adigun.
Senate President Bukola Saraki has relieved of their duties, ninety eight special assistants in his office due to redundancy.
"So, it is an exercise that has now been concluded and we have determined who is good enough to continue, who needs to give way and who may likely come in", he said.
"This is important for the efficiency of the office".
The office of the senate president had conducted a staff audit earlier in the year to thin down the number of aides, which was about 300 at that time. "It was meant to reposition the office to ensure that the office is more strengthened". The last 26 months were good enough to determine who would fit into his agenda for the next 22 months of the lifespan of this Senate.
The affected aides 80% of which were largely believed to be inherited staff were issued sack letters through the office of the Chief of staff, Hakeem Baba-Ahmed.
A number of the affected aides were Staff of the National Assembly who were deployed to the office of the Senate President, while some others were engaged ouside the National Assembly.
The first category of workers are those that have been found capable and competent to continue with their job, like all the entire members of the media unit.
He explained that two years was enough for the Senate President's Office to determine the aides, who could be retained and those who had not added value to the office.
"The third category covers those whose services within the last two years were not all that satisfactory in the eye of the committee set up by the Senate President to carry out the repositioning exercise of his office".
"There is also a second category of people who were seconded from the National Assembly Service Commission to the office of the Senate President and in this exercise some of them were told to revert to bureaucracy where they were from the beginning".
Saraki, who was represented by Senator David Umaru, the Chairman, Senate Committee on Judiciary, Human Rights and Legal Matters, said investors would only invest in an environment where there was a functional judicial system.
Saraki said that ensuring effective access to justice was one of the major challenges of the justice system and the senate was committed to working with partners to make the system simpler and faster.
