Both decisions of Mr. Sirisena - sacking Mr. Wickremesinghe and dissolving Parliament - have raised serious questions about constitutional validity.
The political turmoil in Sri Lanka deepened on Friday, November 9, after President Maithripala Sirisena dissolved the Parliament, calling for early elections in the country on January 5, nearly 2 years ahead of schedule.
The Agence France-Presse cited an unnamed minister as saying that "the election is likely to be held in early January" rather than the scheduled date in 2020.
"We are prepared to go for an election, but this is illegal".
"As a friend of Sri Lanka, the United Kingdom calls on all parties to uphold the constitution and respect democratic institutions and processes", Field said.
The crisis started two weeks ago when Sirisena sacked Prime Minister Ranil Wickramasinghe and named Rajapaksa as his successor.
Sirisena is now gambling that a new election will secure the backing for Mahinda Rajapakse, over ousted prime minister Ranil Wickremesinghe, who has refused to give up office.
The United National Party (UNP) has rejected the dissolution of the Parliament while accusing the President of robbing the people of their rights and democracy.
Earlier on Friday, United People's Freedom Alliance spokesperson Keheliya Rambukwella told reporters that Rajapaksa needs at least eight more votes in the 225-member assembly to reach the majority mark of 113.
Trump slams 'stupid question' from female reporter, calls April Ryan a 'loser'
Trump also criticized American Urban Radio Networks reporter April Ryan , calling her a "loser ". During the press conference, he told her to sit down because he hadn't called on her.
"Maithripala Sirisena dissolved a parliament where we enjoyed a majority", he said.
Sirisena's supporters had been irked by Speaker Karu Jayasuriya's announcement that he was going to call for a vote for either party to prove their support.
The party said in a Twitter message that it will meet the elections commissioner to discuss the constitutionality of Sirisena's move.
The leftist People's Liberation Front (JVP), which regards the sacking of Wickremesinghe as unconstitutional, accused Sirisena of trying to consolidate his power grab.
Lawmakers wanted a vote on Sirisena's decision to fire Wickremesinghe and a majority said they believed the current situation is illegal, the speaker said Monday.
"Dissolving parliament at this time is illegal and goes against the constitution", JVP general secretary Tilvin Silva told reporters. Wickremesinghe has insisted his firing is unconstitutional and demanded that Parliament be summoned to prove his majority.
This is despite several legislators saying they were offered millions of dollars to switch allegiance.
The EU said Friday, before the dissolution, that the crisis had scarred the Indian Ocean island's global reputation.
"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. He can only plunge the country from one crisis to another and take the country down the path of Myanmar, or turning it into a banana republic where the law and the constitution do not matter.
