The Prime Minister of the Central Asian republic of Kyrgyzstan, Azim Isabekov, has resigned amid growing political turmoil.
President Bakiev faces the threat of more street protests
A moderate opposition leader, Almaz Atambayev, has been named in his place.
The appointment, initiated by President Kurmanbek Bakiev, could be an attempt to appease his opponents, who have called for him to step down
It is the first time an opposition politician has been made a prime minister in Central Asia.
But is the appointment a sign of a healthy democracy, or of a weak government that is struggling to survive?
The Kyrgyz government says its doing its best to preserve stability, and that this appointment shows that President Bakiev is willing to compromise.
The move could indeed lower the political temperature, but it is not likely to satisfy Mr Bakiev's more radical opponents.
They are led by Felix Kulov, the president's former ally, who was until two months ago himself the prime minister.
In early April, Mr Kulov and his supporters plan to call for the president's resignation in street protests that they say will be similar to those that brought Mr Bakiev to power in 2005, when he ousted his predecessor Askar Akaev.
Since then, his critics say, Mr Bakiev has failed to deliver on promises to fight corruption and lift the country out of poverty.
Kyrgyzstan's political troubles are also of concern beyond its borders.
America's only remaining military base in Central Asia lies just outside the capital Bishkek. It is a crucial operation that supplies NATO troops in Afghanistan.
