Sri Lanka is seeking a way out of political and economic chaos after its President Gotabaya Rajapaksa resigned and fled the country.
Prime Minister Ranil Wickremesinghe was sworn in as temporary leader on Friday and has the ruling party's backing to take the role permanently.
This makes him the favourite when a new president is chosen next week, but may prove unacceptable to protesters.
Mr Rajapaksa fled to Singapore, sparking celebrations in the street.
He and his family have been blamed for a deep economic crisis, with Sri Lankans facing acute shortages of food, fuel and other basic supplies.
Businesses and shops reopened in the capital, Colombo, on Friday morning after a curfew was lifted, but soldiers could still be seen on major roads.
