Prime Minister Yingluck Shinawatra has no plan to dissolve the House of Representatives and call a general election, says a party spokesman.
Pheu Thai deputy spokesman Anusorn Eiamsa-ard was responding on Saturday to media reports that the House would be dissolved after the 2014 budget bill passes parliament and the government completes more transfers of civil servants.
Critics of the government say Pheu Thai might feel it could win an even bigger mandate from the public later this year, after which it would feel emboldened to push through some of its more contentious plans.
Those plans include constitutional amendments and a reconciliation bill that could help bring the party's exiled de facto leader Thaksin Shinawatra back to Thailand.
Mr Anusorn reiterated that the government, which took office in August 2011, still had two more years left in its term and it would be pointless to dissolve the House at this time.
He said moves by several groups of people to topple the government were supported by the same people who had backed the 2006 coup that ousted Thaksin, forced out the late Samak Sundaravej via the courts, and forced his successor, Somchai Wongsawat, to resign in 2008.
