The Maoists have decided to end the six-month long obstruction of the House on Wednesday.
"We made a unilateral decision to resume House business at a parliamentary party meeting this morning," Maoist spokesperson Dina Nath Sharma said.
Sharma said Maoist Chairman Pushpa Kamal Dahal will address the House on Thursday to explain why they made the decision to resume the House after months of obstruction.
Maoists let the parliament open for business for three days in November in order to pass the budget.
"As a responsible democratic party we decided to allow the House to run," Sharma said. "We want to send out a message that this government does not have one iota of morality to address the demands of the opposition."
Sharma said the Maoist struggle was not over. "We are going to continue our struggle in the parliament. We haven't given up our demands."
The government is pleased the Maoists took a good decision, said UML's Chief Whip Bhim Acharya, adding: "Their decision to obstruct the House was unrealistic. So they had to take the decision unilaterally."
On Tuesday, Maoist Chairman Pushpa Kamal Dahal had said he wanted direct talks with Delhi because Nepal's 'puppet' government was run by 'masters' from Delhi.
Earlier Maoist vice chairman Narayan Kaji Shrestha had told reporters that Dahal was being sarcastic about the government's inability to make decisions without India's input.
Sharma also said the news that Dahal was joking about having talks with Delhi was 'nonsense'. "The Chairman spoke in full consciousness and no one can retract the statement, but him," he said.
