A tale of two prime ministers in Sri Lanka 

There's been political trouble in Sri Lanka over the past two weeks after President Maithripala Sirisena dismissed prime minister Ranil Wickremesinghe and appointed former president Mahinda Rajapaksa in his place.

It is not clear that the president had the authority to make such a decision though, and Mr Wickremesinghe has refused to vacate the prime minister's residence.

Which has left Sri Lanka in the unusual position of having two men claiming to be prime minister.
