Raila's team postponed the swearing-in ceremony in anticipation for talks with Uhuru Kenyatta.
Mr Odinga took off Monday evening after the government threatened to arrest and charge him with treason if he was to defy the warning from Attorney General Prof Githu Muigai, who wanted him to back off from the oath taking plan.
Meanwhile, four Nasa principals – Raila Odinga, Musalia Mudavadi, Moses Wetangula and Kalonzo Musyoka - will be retreating over the weekend to tighten the game plan to resist President Uhuru Kenyatta's Jubilee administration.
This will be the first time in two months for Wiper leader Kalonzo Musyoka to attend the group meeting. Mr Musyoka has been in Germany attending to his sick wife Pauline.
Mr Musyoka is also expected at the burial ceremony of former Kitui West MP Francis Nyenze on Tuesday next week.
The opposition has been in the eye of the storm after it called off Raila's swearing in as the People's President in a Mombasa hotel on Sunday.
Nasa is said to have devised a new message to return to its supporters after the fall of the much hyped swearing-in plan which the western envoys, split in Nasa leadership pushed for the abandonment.
The new strategy ‘We're not giving up the fight, don't lose faith. We're revitalising the resistance, there will be a swearing-in’ is the expected to be part of the strategy to win back support after millions who have since lost hope in the leadership of Nasa.
