COLOMBO, Sri Lanka — Sri Lanka’s President Maithripala Sirisena on Friday dissolved Parliament and called for fresh elections amid a deepening political crisis.

An official notification signed by Sirisena announced the dissolution of Parliament effective at midnight Friday.

The notice said the names of candidates for new elections will be called before Nov. 26, and the election will be held on Jan. 5. The new Parliament is to be convened on Jan. 17.

Sri Lanka has been in a political crisis since Oct. 26, when Sirisena fired his prime minister, Ranil Wickremesinghe, and replaced him with former strongman Mahinda Rajapaksa.

Wickremesinghe has insisted his firing is unconstitutional. He has refused to vacate his official residence and demanded that Parliament be summoned immediately to prove he had support among its members.

Sirisena had suspended Parliament for two weeks in a move Wickremesinghe’s backers said was designed to buy time to shore up support.

There were calls both locally and internationally to convene Parliament to end the impasse.

Amid the pressure, Sirisena announced Parliament would be summoned Nov.14. He maintained his choice for prime minister, Mahinda Rajapaksa, had a majority in Parliament. However, the decision to dissolve Parliament shows that is not so, observers say.

“The dissolution clearly indicates that Mr. Sirisena has grossly misjudged and miscalculated the support that he might or could secure to demonstrate support in the Parliament,” said Bharath Gopalaswamy, director at New Delhi-based analyst group Atlantic Council’s South Asia Center.

“At the end of the day, he is a victim of his own homegrown crisis.”

Wickremesinghe’s camp is likely to contest Sirisena’s move because of constitutional provisions stating a Parliament can’t be dissolved until four and a half years after its inception. The current Parliament was elected in August 2015.

“It’s totally unconstitutional,” said Harsha de Silva, a member of Wickremesinghe’s United National Party and a former minister.

“Sirisena has relegated the constitution to toilet paper. We will fight this dictator to the end.”

The party said in a Twitter message that it will meet the elections commissioner to discuss the constitutionality of Sirisena’s move.

The U.S State Department said on its Twitter page that it is deeply concerned by news the Sri Lanka Parliament will be dissolved, “further deepening the political crisis.”

“As a committed partner of Sri Lanka, we believe democratic institutions and processes need to be respected to ensure stability and prosperity.”

Earlier, U.S. Rep. Eliot Engel, the top-ranking Democrat on the House Foreign Affairs Committee, and two other lawmakers wrote to the Sri Lankan president warning that actions circumventing the democratic process could impact U.S. assistance — including a planned five-year aid package from the Millennium Challenge Corporation worth hundreds of millions of dollars.

“We fear that recent actions, if not corrected, will threaten your country’s democratic development and derail the progress made in recent years,” the three lawmakers said in a letter, a copy of which was obtained by The Associated Press.

Rajapaksa indicated what was coming hours before the dissolution in a speech. He said the government must go to the people for confirmation on whether the president made the correct decision when he appointed him as prime minister.
