Sri Lanka's newly appointed Prime Minister Mahinda Rajapaksa

Sri Lanka was plunged into crisis on Friday when President Maithripala Sirisena sacked Wickremesinghe and swore in ex-president Mahinda Rajapaksa to replace him, breaking up a fragile coalition governing the country. Sirisena also suspended parliament, to the fury of Wickremesinghe's supporters, who say the president is trying to prevent lawmakers from keeping him in power.
