NASA supporters have been given access to Uhuru Park contrary to the planned blockade by the police.
Anti-riot police officers who were spotted at Uhuru Park on Tuesday at dawn were later on withdrawn.
This was after they were reportedly told to leave the park for NASA youths who are streamed in at the grounds from as early as 6am.
Homabay Copunty women representative Gladys Wanga has already arrived at the venue.
The Nairobi Business Community had also claimed access of the venue for what they termed a medical camp.
Among the services the business community have planned at the rally is circumsicion.
This has drawn a lot of curiosity as many people perceived to be NASA supporters are from a community that does not circumcise traditionally.
NASA leaders plan to swear in Raila by 12 am.
