Several SLPP MPs led by their national organizer Namal Rajapaksa are planning to sit in the opposition, political sources said.
They have also moved to boycott the government parliamentary group, after its politburo decided to field an own presidential candidate without supporting incumbent Ranil Wickremesinghe.
Furthermore, the state ministers loyal to Rajapaksa are to resign from their positions this week, said the sources.
Parliament sittings from tomorrow (06) are expected to be heated, with several crossovers too, tipped to take place.
Govt. loses majority?
Critics say the government has lost its majority in parliament following the SLPP decision to field a candidate.
Previously, it had around 117 supporters, but now it has come down to less than 100.
As a result, it will find passing an act with simple majority to be difficult.
But, Nimal Lanza of the New Alliance says they are prepared to show a majority support for the government when sittings begin.
