After Sri Lanka's President Maithripala Sirisena dismissed Ranil Wickremesinghe as prime minister, replacing him with the island nation's former strongman president Mahinda Rajapaksa, Mr Wickremesinghe has refused recognise his shock dismissal, in an unfolding constitutional crisis. Mr Wickremesinghe continued to occupy Temple Trees, the official residence of the prime minister, and insisted in a letter to Mr Sirisena that he was still in office. He has said that he can be removed only by parliament where his party enjoys a majority. He urged the speaker to convene the parliament on Sunday to prove he still retained his parliamentary majority. Mr Wickremesinghe also vowed to seek legal action against what he condemned as an unconstitutional move against him.
