Xiomara Castro was sworn in here Thursday as the first female president of Honduras, a country mired in a severe economic crisis and plagued by the scourges of corruption and drug trafficking.

The new head of state also must deal with a rebellion within her own party, following a revolt last Friday by a large group of members of her leftist Libre party who refused to accept her attempt to install a member of an allied party as congressional speaker.

As a result of the schism within parliament, rival candidates are claiming to be head of Congress and Castro was forced to take the oath of office before Judge Karla Rivera at the National Stadium in Tegucigalp.
