Prime Minister Ranil Wickremesinghe is expected to meet President Gotabhaya Rajapaksa today.
At the meeting, the Prime Minister will discuss arrangements for transition of power with the newly-elected President.
The UNP is sharply divided on whether the party should support the immediate dissolution of the current Parliament.
Parliament cannot be dissolved without the support of 2/3 of MPs.
A sizable proportion of UNP MPs are of the view that an immediate Parliamentary election should not be held.
